Podcasts about OpenJDK

En este episodio, me sumerjo en el lanzamiento de Ubuntu 25.10 "Questing Quokka" y analizo las novedades más importantes y controvertidas. Aunque estoy en el mundo Rolling Release (ArchLinux), me gusta centrarme en lo que traen las nuevas versiones.Temas clave y soluciones prácticas:Seguridad y Rendimiento: Hablo sobre la gran novedad que ha generado debate: la incorporación experimental de sudo-rs y rust-coreutils. Analizo por qué Canonical está reescribiendo estas utilidades esenciales en Rust y aclaro si esto realmente rompe con la filosofía GNU/Linux.Escritorio Productivo: Revisamos el nuevo entorno GNOME 49, con mejoras como los controles multimedia en la pantalla de bloqueo y el reemplazo de herramientas como el terminal (por Ptyxis) y el visor de imágenes (por Loupe).Herramientas para Desarrolladores: Si eres desarrollador o sysadmin, esta versión trae actualizaciones significativas: Python 3.14, Rust 1.85, OpenJDK 25 y soporte experimental para TPM 2.0.Bonus Práctico: Pacstall: Te muestro qué es Pacstall, un gestor de paquetes alternativo en la línea de los PKGBUILD de ArchLinux, y cómo puede facilitar la instalación de software de terceros en tu sistema Ubuntu. Una herramienta esencial para estar "a la última".Escucha y descubre todas las soluciones que trae Ubuntu 25.10 para "cualquier cosa que quieras hacer con Linux".Más información y enlaces en las notas del episodio

Welcome to another episode of the Foojay Podcast! Just like in the previous episode, I bring you conversations from two of Europe's premier Java conferences - Devoxx in Belgium and JFall in the Netherlands.At these conferences, I had the opportunity to speak with members of the Java community about topics ranging from the evolution of Java itself to mobile development, performance optimization, and even automotive security.My first guest is Johan Vos, a Java Champion who takes us on a journey through Java's history - from porting Java to Linux in 1995 to his current work on bringing Java and JavaFX to mobile and embedded devices through the Java On Mobile project.Then we'll hear from Stephen Chin, author of "The Definitive Guide to Modern Java Clients with JavaFX," who shares insights on building cross-platform client applications and reflects on how his daughter has followed in his footsteps to become a published author and technology educator.From JFall, Joseph Phillips joins us to discuss Java's evolution, the differences between REST and gRPC, and whether virtual threads have replaced the need for async implementations in modern Java applications.Next, François Martin walks us through the world of Java performance benchmarking with JMH - the Java Microbenchmark Harness - and explains why it's so valuable for comparing different implementations and optimizing code.Wouter De Geus shares his inspiring journey from finance and mathematics into Java development, and how his employer, the Dutch Tax Authority, supports open-source contributions and the Java community.And finally, Roald Nefs demonstrates something truly unique - using Java and the Foreign Function & Memory API to hack into automotive systems, revealing important security considerations for both hardware and software.Content00:00 Introduction of topics and guests02:11 Johan Voshttps://www.linkedin.com/in/johanvos/History of Java on LinuxHow the Java language and runtime are stable and evolving at the same timeLooking at the future of Write-Once-Run-Everywhere with Java(FX) on Mobilehttps://openjdk-mobile.github.io/19:04 Stephen Chinhttps://www.linkedin.com/in/steveonjava/Author of "The Definitive Guide to Modern Java Clients with JavaFX"Cassandra Chin: https://www.linkedin.com/in/cassandra-chin-developer/ Her book: https://www.amazon.nl/Raising-Young-Coders-Teaching-Programming/dp/B0DVBQZ48323:22 Joseph Phillipshttps://foojay.social/deck/@infosec812Java evolutions, communityREST versus gRPCDo we still need async or are virtual threads a better solution?27:49 François Martinhttps://www.linkedin.com/in/fran%C3%A7oismartinJava performance micro benchmarks with jmhhttps://github.com/openjdk/jmh33:30 Wouter De Geushttps://www.linkedin.com/in/wadegeus/Moved from finance to software developmentContributing back to the open-source community39:33 Roald Nefshttps://www.linkedin.com/in/roaldnefs/Hacking cars with the FFM APIHardware and software security concernsWhat you can learn from the Java community46:29 Outro

Dans cet épisode, Emmanuel, Katia et Guillaume discutent de Spring 7, Quarkus, d'Infinispan et Keycloak. On discute aussi de projets sympas comme Javelit, de comment démarre une JVM, du besoin d'argent de NTP. Et puis on discute du changement de carrière d'Emmanuel. Enregistré le 14 novembre 2025 Téléchargement de l'épisode LesCastCodeurs-Episode-332.mp3 ou en vidéo sur YouTube. News Emmanuel quitte Red Hat après 20 ans https://emmanuelbernard.com/blog/2025/11/13/leaving-redhat/ Langages Support HTTP/3 dans le HttpClient de JDK 26 - https://inside.java/2025/10/22/http3-support/ JDK 26 introduit le support de HTTP/3 dans l'API HttpClient existante depuis Java 11 HTTP/3 utilise le protocole QUIC sur UDP au lieu de TCP utilisé par HTTP/2 Par défaut HttpClient préfère HTTP/2, il faut explicitement configurer HTTP/3 avec Version.HTTP_3 Le client effectue automatiquement un downgrade vers HTTP/2 puis HTTP/1.1 si le serveur ne supporte pas HTTP/3 On peut forcer l'utilisation exclusive de HTTP/3 avec l'option H3_DISCOVERY en mode HTTP_3_URI_ONLY HttpClient apprend qu'un serveur supporte HTTP/3 via le header alt-svc (RFC 7838) et utilise cette info pour les requêtes suivantes La première requête peut utiliser HTTP/2 même avec HTTP/3 préféré, mais la seconde utilisera HTTP/3 si le serveur l'annonce L'équipe OpenJDK encourage les tests et retours d'expérience sur les builds early access de JDK 26 Librairies Eclispe Jetty et CometD changent leurs stratégie de support https://webtide.com/end-of-life-changes-to-eclipse-jetty-and-cometd/ À partir du 1er janvier 2026, Webtide ne publiera plus Jetty 9/10/11 et CometD 5/6/7 sur Maven Central Pendant 20 ans, Webtide a financé les projets Jetty et CometD via services et support, publiant gratuitement les mises à jour EOL Le comportement des entreprises a changé : beaucoup cherchent juste du gratuit plutôt que du véritable support Des sociétés utilisent des versions de plus de 10 ans sans migrer tant que les correctifs CVE sont gratuits Cette politique gratuite a involontairement encouragé la complaisance et retardé les migrations vers versions récentes MITRE développe des changements au système CVE pour mieux gérer les concepts d'EOL Webtide lance un programme de partenariat avec TuxCare et HeroDevs pour distribuer les résolutions CVE des versions EOL Les binaires EOL seront désormais distribués uniquement aux clients commerciaux et via le réseau de partenaires Webtide continue le support standard open-source : quand Jetty 13 sortira, Jetty 12.1 recevra des mises à jour pendant 6 mois à un an Ce changement vise à clarifier la politique EOL avec une terminologie industrielle établie Améliorations cloud du SDK A2A Java https://quarkus.io/blog/quarkus-a2a-cloud-enhancements/ Version 0.3.0.Final du SDK A2A Java apporte des améliorations pour les environnements cloud et distribués Composants en mémoire remplacés par des implémentations persistantes et répliquées pour environnements multi-instances JpaDatabaseTaskStore et JpaDatabasePushNotificationConfigStore permettent la persistance des tâches et configurations en base PostgreSQL ReplicatedQueueManager assure la réplication des événements entre instances A2A Agent via Kafka et MicroProfile Reactive Messaging Exemple complet de déploiement Kubernetes avec Kind incluant PostgreSQL, Kafka via Strimzi, et load balancing entre pods Démonstration pratique montrant que les messages peuvent être traités par différents pods tout en maintenant la cohérence des tâches Architecture inspirée du SDK Python A2A, permettant la gestion de tâches asynchrones longues durée en environnement distribué Quarkus 3.29 sort avec des backends de cache multiples et support du débogueur Qute https://quarkus.io/blog/quarkus-3-29-released/ Possibilité d'utiliser plusieurs backends de cache simultanément dans une même application Chaque cache peut être associé à un backend spécifique (par exemple Caffeine et Redis ou Infinispan) Support du Debug Adapter Protocol (DAP) pour déboguer les templates Qute directement dans l'IDE et dans la version 3.28 Configuration programmatique de la protection CSRF via une API fluent Possibilité de restreindre les filtres OIDC à des flux d'authentification spécifiques avec annotations Support des dashboards Grafana personnalisés via fichiers JSON dans META-INF/grafana/ Extension Liquibase MongoDB supporte désormais plusieurs clients simultanés Amélioration significative des performances de build avec réduction des allocations mémoire Parallélisation de tâches comme la génération de proxies Hibernate ORM et la construction des Jar Et l'utilisation des fichiers .proto est plus simple dans Quarkus avbec Quarkus gRPC Zero https://quarkus.io/blog/grpc-zero/ c'est toujours galere des fichiers .proto car les generateurs demandent des executables natifs maintenant ils sont bundlés dans la JVM et vous n'avez rien a configurer cela utilise Caffeine pour faire tourner cela en WASM dans la JVM Spring AI 1.1 est presque là https://spring.io/blog/2025/11/08/spring-ai-1-1-0-RC1-available-now support des MCP tool caching pour les callback qui reduit les iooerations redondantes Access au contenu de raisonnement OpenAI Un

https://spring.io/blog/2025/11/05/spring-grpc-next-steps Spring gRPC 1.0 arrive prochainement avec support de Spring Boot 4 L'intégration dans Spring Boot 4.0 est reportée, prévue pour Spring Boot 4.1 Les coordonnées Maven restent sous org.springframework.grpc pour la version 1.0 Le jar spring-grpc-test est renommé en spring-grpc-test-spring-boot-autoconfigure Les packages d'autoconfiguration changent de nom nécessitant de modifier les imports Les dépendances d'autoconfiguration seront immédiatement dépréciées après la release 1.0 Migration minimale attendue pour les projets utilisant déjà la version 0.x La version 1.0.0-RC1 sera publiée dès que possible avant la version finale Spring arrete le support reactif d'Apache Pulsar https://spring.io/blog/2025/10/29/spring-pulsar-reactive-discontinued logique d'évaluer le temps passé vs le nombre d'utilisateurs c'est cependant une tendance qu'on a vu s'accélerer Spring 7 est sorti https://spring.io/blog/2025/11/13/spring-framework-7-0-general-availability Infrastructure Infinispan 16.0 https://infinispan.org/blog/2025/11/10/infinispan-16-0 Ajout majeur : migration en ligne sans interruption pour les nœuds d'un cluster (rolling upgrades) (infinispan.org) Messages de clustering refaits avec Protocol Buffers + ProtoStream : meilleure compatibilité, schéma évolutif garanti (infinispan.org) Console Web améliorée API dédiée de gestion des schémas (SchemasAdmin) pour gérer les schémas ProtoStream à distance (infinispan.org) Module de requête (query) optimisé : support complet des agrégations (sum, avg …) dans les requêtes indexées en cluster grâce à l'intégration de Hibernate Search 8.1 (infinispan.org) Serveur : image conteneur minimalisée pour réduire la surface d'attaque (infinispan.org) démarrage plus rapide grâce à séparation du démarrage cache/serveur (infinispan.org) caches pour connecteurs (Memcached, RESP) créés à la demande (on-demand) et non à l'initiaton automatique (infinispan.org) moteur Lua 5.1 mis à jour avec corrections de vulnérabilités et opérations dangereuses désactivées (infinispan.org) Support JDK : version minimale toujours JDK 17 (infinispan.org) prise en charge des threads virtuels (virtual threads) et des fonctionnalités AOT (Ahead-of-Time) de JDK plus récentes (infinispan.org) Web Javelit, une nouvelle librairie Java inspirée de Streamlit pour faire facilement et rapidement des petites interfaces web https://glaforge.dev/posts/2025/10/24/javelit-to-create-quick-interactive-app-frontends-in-java/ Site web du projet : https://javelit.io/ Javelit : outil pour créer rapidement des applications de données (mais pas que) en Java. Simplifie le développement : élimine les tracas du frontend et de la gestion des événements. Transforme une classe Java en application web en quelques minutes. Inspiré par la simplicité de Streamlit de l'écosystème Python (ou Gradio et Mesop), mais pour Java. Développement axé sur la logique : pas de code standard répétitif (boilerplate), rechargement à chaud. Interactions faciles : les widgets retournent directement leur valeur, sans besoin de HTML/CSS/JS ou gestion d'événements. Déploiement flexible : applications autonomes ou intégrables dans des frameworks Java (Spring, Quarkus, etc.). L'article de Guillaume montre comment créer une petite interface pour créer et modifier des images avec le modèle génératif Nano Banana Un deuxième article montre comment utiliser Javelit pour créer une interface de chat avec LangChain4j https://glaforge.dev/posts/2025/10/25/creating-a-javelit-chat-interface-for-langchain4j/ Améliorer l'accessibilité avec les applis JetPack Compose https://blog.ippon.fr/2025/10/29/rendre-son-application-accessible-avec-jetpack-compose/ TalkBack est le lecteur d'écran Android qui vocalise les éléments sélectionnés pour les personnes malvoyantes Accessibility Scanner et les outils Android Studio détectent automatiquement les problèmes d'accessibilité statiques Les images fonctionnelles doivent avoir un contentDescription, les images décoratives contentDescription null Le contraste minimum requis est de 4.5:1 pour le texte normal et 3:1 pour le texte large ou les icônes Les zones cliquables doivent mesurer au minimum 48dp x 48dp pour faciliter l'interaction Les formulaires nécessitent des labels visibles permanents et non de simples placeholders qui disparaissent Modifier.semantics permet de définir l'arbre sémantique lu par les lecteurs d'écran Les propriétés mergeDescendants et traversalIndex contrôlent l'ordre et le regroupement de la lecture Diriger le navigateur Chrome avec le modèle Gemini Computer Use https://glaforge.dev/posts/2025/11/03/driving-a-web-browser-with-gemini-computer-use-model-in-java/ Objectif : Automatiser la navigation web en Java avec le modèle "Computer Use" de Gemini 2.5 Pro. Modèle "Computer Use" : Gemini analyse des captures d'écran et génère des actions d'interface (clic, saisie, etc.). Outils : Gemini API, Java, Playwright (pour l'interaction navigateur). Fonctionnement : Boucle agent où Gemini reçoit une capture, propose une action, Playwright l'exécute, puis une nouvelle capture est envoyée à Gemini. Implémentation clé : Toujours envoyer une capture d'écran à Gemini après chaque action pour qu'il comprenne l'état actuel. Défis : Lenteur, gestion des CAPTCHA et pop-ups (gérables). Potentiel : Automatisation des tâches web répétitives, création d'agents autonomes. Data et Intelligence Artificielle Apicurio ajoute le support de nouveaux schema sans reconstruire Apicurio https://www.apicur.io/blog/2025/10/27/custom-artifact-types Apicurio Registry 3.1.0 permet d'ajouter des types d'artefacts personnalisés au moment du déploiement sans recompiler le projet Supporte nativement OpenAPI, AsyncAPI, Avro, JSON Schema, Protobuf, GraphQL, WSDL et XSD Trois approches d'implémentation disponibles : classes Java pour la performance maximale, JavaScript/TypeScript pour la facilité de développement, ou webhooks pour une flexibilité totale Configuration via un simple fichier JSON pointant vers les implémentations des composants personnalisés Les scripts JavaScript sont exécutés via QuickJS dans un environnement sandboxé sécurisé Un package npm TypeScript fournit l'autocomplétion et la sécurité de type pour le développement Six composants optionnels configurables : détection automatique de type, validation, vérification de compatibilité, canonicalisation, déréférencement et recherche de références Cas d'usage typiques : formats propriétaires internes, support RAML, formats legacy comme WADL, schémas spécifiques à un domaine métier Déploiement simple via Docker en montant les fichiers de configuration et scripts comme volumes Les performances varient selon l'approche : Java offre les meilleures performances, JavaScript un bon équilibre, webhooks la flexibilité maximale Le truc interessant c'est que c'est Quarkus based et donc demandait le rebuilt donc pour eviter cela, ils ont ajouter QuickJS via Chicorey un moteur WebAssembly GPT 5.1 pour les développeurs est sorti. https://openai.com/index/gpt-5-1-for-developers/ C'est le meilleur puisque c'est le dernier :slightly_smiling_face: Raisonnement Adaptatif et Efficace : GPT-5.1 ajuste dynamiquement son temps de réflexion en fonction de la complexité de la tâche, le rendant nettement plus rapide et plus économique en jetons pour les tâches simples, tout en maintenant des performances de pointe sur les tâches difficiles. Nouveau Mode « Sans Raisonnement » : Un mode (reasoning_effort='none') a été introduit pour les cas d'utilisation sensibles à la latence, permettant une réponse plus rapide avec une intelligence élevée et une meilleure exécution des outils. Cache de Prompt Étendu : La mise en cache des invites est étendue jusqu'à 24 heures (contre quelques minutes auparavant), ce qui réduit la latence et le coût pour les interactions de longue durée (chats multi-tours, sessions de codage). Les jetons mis en cache sont 90 % moins chers. Améliorations en Codage : Le modèle offre une meilleure personnalité de codage, une qualité de code améliorée et de meilleures performances sur les tâches d'agenticité de code, atteignant 76,3 % sur SWE-bench Verified. Nouveaux Outils pour les Développeurs : Deux nouveaux outils sont introduits ( https://cookbook.openai.com/examples/build_a_coding_agent_with_gpt-5.1 ) : L'outil apply_patch pour des modifications de code plus fiables via des diffs structurés. L'outil shell qui permet au modèle de proposer et d'exécuter des commandes shell sur une machine locale, facilitant les boucles d'inspection et d'exécution. Disponibilité : GPT-5.1 (ainsi que les modèles gpt-5.1-codex) est disponible pour les développeurs sur toutes les plateformes API payantes, avec les mêmes tarifs et limites de débit que GPT-5. Comparaison de similarité d'articles et de documents avec les embedding models https://glaforge.dev/posts/2025/11/12/finding-related-articles-with-vector-embedding-models/ Principe : Convertir les articles en vecteurs numériques ; la similarité sémantique est mesurée par la proximité de ces vecteurs. Démarche : Résumé des articles via Gemini-2.5-flash. Conversion des résumés en vecteurs (embeddings) par Gemini-embedding-001. Calcul de la similarité entre vecteurs par similarité cosinus. Affichage des 3 articles les plus pertinents (>0.75) dans le frontmatter Hugo. Bilan : Approche "résumé et embedding" efficace, pragmatique et améliorant l'engagement des lecteurs. Outillage Composer : Nouveau modèle d'agent rapide pour l'ingénierie logicielle - https://cursor.com/blog/composer Composer est un modèle d'agent conçu pour l'ingénierie logicielle qui génère du code quatre fois plus rapidement que les modèles similaires Le modèle est entraîné sur de vrais défis d'ingénierie logicielle dans de grandes bases de code avec accès à des outils de recherche et d'édition Il s'agit d'un modèle de type mixture-of-experts optimisé pour des réponses interactives et rapides afin de maintenir le flux de développement L'entraînement utilise l'apprentissage par renforcement dans divers environnements de développement avec des outils comme la lecture de fichiers, l'édition, les commandes terminal et la recherche sémantique Cursor Bench est un benchmark d'évaluation basé sur de vraies demandes d'ingénieurs qui mesure la correction et le respect des abstractions du code existant Le modèle apprend automatiquement des comportements utiles comme effectuer des recherches complexes, corriger les erreurs de linter et écrire des tests unitaires L'infrastructure d'entraînement utilise PyTorch et Ray avec des kernels MXFP8 pour entraîner sur des milliers de GPUs NVIDIA Le système exécute des centaines de milliers d'environnements de codage sandboxés concurrents dans le cloud pour l'entraînement Composer est déjà utilisé quotidiennement par les développeurs de Cursor pour leur propre travail Le modèle se positionne juste derrière GPT-5 et Sonnet 4.5 en termes de performance sur les benchmarks internes Rex sur l'utilisation de l'IA pour les développeurs, un gain de productivité réel et des contextes adaptés https://mcorbin.fr/posts/2025-10-17-genai-dev/ Un développeur avec 18 ans d'expérience partage son retour sur l'IA générative après avoir changé d'avis Utilise exclusivement Claude Code dans le terminal pour coder en langage naturel Le "vibe coding" permet de générer des scripts et interfaces sans regarder le code généré Génération rapide de scripts Python pour traiter des CSV, JSON ou créer des interfaces HTML Le mode chirurgien résout des bugs complexes en one-shot, exemple avec un plugin Grafana fixé en une minute Pour le code de production, l'IA génère les couches repository, service et API de manière itérative, mais le dev controle le modele de données Le développeur relit toujours le code et ajuste manuellement ou via l'IA selon le besoin L'IA ne remplacera pas les développeurs car la réflexion, conception et expertise technique restent essentielles La construction de produits robustes, scalables et maintenables nécessite une expérience humaine L'IA libère du temps sur les tâches répétitives et permet de se concentrer sur les aspects complexes ce que je trouve interessant c'est la partie sur le code de prod effectivement, je corrige aussi beaucoup les propositions de l'IA en lui demandant de faire mieux dans tel ou tel domaine Sans guide, tout cela serait perdu Affaire a suivre un article en parallele sur le métier de designer https://blog.ippon.fr/2025/11/03/lia-ne-remplace-pas-un-designer-elle-amplifie-la-difference-entre-faire-et-bien-faire/ Plus besoin de se rappeler les racourcis dans IntelliJ idea avec l'universal entry point https://blog.jetbrains.com/idea/2025/11/universal-entry-point-a-single-entry-point-for-context-aware-coding-assistance/ IntelliJ IDEA introduit Command Completion, une nouvelle façon d'accéder aux actions de l'IDE directement depuis l'éditeur Fonctionne comme la complétion de code : tapez point (.) pour voir les actions contextuelles disponibles Tapez double point (..) pour filtrer et n'afficher que les actions disponibles Propose des corrections, refactorings, génération de code et navigation selon le contexte Complète les fonctionnalités existantes sans les remplacer : raccourcis, Alt+Enter, Search Everywhere Facilite la découverte des fonctionnalités de l'IDE sans interrompre le flux de développement En Beta dans la version 2025.2, sera activé par défaut dans 2025.3 Support actuel pour Java et Kotlin, avec actions spécifiques aux frameworks comme Spring et Hibernate Homebrew, package manage pour macOS et Linux passe en version 5 https://brew.sh/2025/11/12/homebrew-5.0.0/ Téléchargements Parallèles par Défaut : Le paramètre HOMEBREW_DOWNLOAD_CONCURRENCY=auto est activé par défaut, permettant des téléchargements concurrents pour tous les utilisateurs, avec un rapport de progression. Support Linux ARM64/AArch64 en Tier 1 : Le support pour Linux ARM64/AArch64 a été promu au niveau "Tier 1" (support officiel de premier plan). Feuille de Route pour les Dépréciations macOS : Septembre 2026 (ou plus tard) : Homebrew ne fonctionnera plus sur macOS Catalina (10.15) et versions antérieures. macOS Intel (x86_64) passera en "Tier 3" (fin du support CI et des binaires précompilés/bottles). Septembre 2027 (ou plus tard) : Homebrew ne fonctionnera plus sur macOS Big Sur (11) sur Apple Silicon ni du tout sur Intel (x86_64). Sécurité et Casks : Dépréciation des Casks sans signature de code. Désactivation des Casks échouant aux vérifications Gatekeeper en septembre 2026. Les options --no-quarantine et --quarantine sont dépréciés pour ne plus faciliter le contournement des fonctionnalités de sécurité de macOS. Nouvelles Fonctionnalités & Améliorations : Support officiel pour macOS 26 (Tahoe). brew bundle supporte désormais l'installation de packages Go via un Brewfile. Ajout de la commande brew info --sizes pour afficher la taille des formulae et casks. La commande brew search --alpine permet de chercher des packages Alpine Linux. Architecture Selon l'analyste RedMonk, Java reste très pertinent dans l'aire de l'IA et des agents https://redmonk.com/jgovernor/java-relevance-in-the-ai-era-agent-frameworks-emerge/ Java reste pertinent à l'ère de l'IA, pas besoin d'apprendre une pile technique entièrement nouvelle. Capacité d'adaptation de Java ("anticorps") aux innovations (Big Data, cloud, IA), le rendant idéal pour les contextes d'entreprise. L'écosystème JVM offre des avantages sur Python pour la logique métier et les applications sophistiquées, notamment en termes de sécurité et d'évolutivité. Embabel (par Rod Johnson, créateur de Spring) : un framework d'agents fortement typé pour JVM, visant le déterminisme des projets avant la génération de code par LLM. LangChain4J : facilite l'accès aux capacités d'IA pour les développeurs Java, s'aligne sur les modèles d'entreprise établis et permet aux LLM d'appeler des méthodes Java. Koog (Jetbrains) : framework d'agents basé sur Kotlin, typé et spécifique aux développeurs JVM/Kotlin. Akka : a pivoté pour se concentrer sur les flux de travail d'agents IA, abordant la complexité, la confiance et les coûts des agents dans les systèmes distribués. Le Model Context Protocol (MCP) est jugé insuffisant, manquant d'explicabilité, de découvrabilité, de capacité à mélanger les modèles, de garde-fous, de gestion de flux, de composabilité et d'intégration sécurisée. Les développeurs Java sont bien placés pour construire des applications compatibles IA et intégrer des agents. Des acteurs majeurs comme IBM, Red Hat et Oracle continuent d'investir massivement dans Java et son intégration avec l'IA. Sécurité AI Deepfake, Hiring … A danger réel https://www.eu-startups.com/2025/10/european-startups-get-serious-about-deepfakes-as-ai-fraud-losses-surpass-e1-3-billion/ Pertes liées aux deepfakes en Europe : > 1,3 milliard € (860 M € rien qu'en 2025). Création de deepfakes désormais possible pour quelques euros. Fraudes : faux entretiens vidéo, usurpations d'identité, arnaques diverses. Startups actives : Acoru, IdentifAI, Trustfull, Innerworks, Keyless (détection et prévention). Réglementation : AI Act et Digital Services Act imposent transparence et contrôle. Recommandations : vérifier identités, former employés, adopter authentification multi-facteurs.

In this Foojay Podcast, we're diving deep into some of the most exciting developments happening within the OpenJDK and TornadoVM projects.At the Devoxx and JFall conferences, we spoke with several speakers and visitors about some of the major themes that are shaping the future of Java development. The first guest is Moritz Halbritter from the Spring Engineering team. He provides us with more insights into Project Leyden and how it's improving Java startup times through ahead-of-time compilation and profiling. We'll learn how Spring Boot developers can already take advantage of these improvements today.Next, we'll hear from John Cecerralli at Azul about performance optimizations, the evolution from x86 to ARM64 architectures, and how OpenJDK Projects bring improvements to the JVM itself at levels we couldn't achieve before.Then, Balkrishna Rawool will guide us through the world of vector databases and explain how Java's Vector API from Project Panama is perfectly positioned for AI use cases, despite its development beginning years before the current AI boom.And finally, we'll meet some of the team members behind TornadoVM - Christos Kotselidis and Michalis Papadimitriou from the University of Manchester - who will explain to us how Java developers can now harness the power of GPUs for AI workloads, running large language models in pure Java without leaving the Java ecosystem. They also explain the connection between TornadoVM and the OpenJDK Project Babylon.00:00 Introduction of topics and guests01:58 Moritz Halbritter* https://www.linkedin.com/in/moritz-halbritter-9301a1b1/* Project Leyden and how it can already be used with Spring* Difference between the approach of Project Leyden and CRaC11:02 John Cecerralli* https://www.linkedin.com/in/john-ceccarelli-95b7041/* OpenJDK evolutions in Project Leyden* Startup time improvements in Azul Prime* Java performance* ARM Graviton17:08 Balkrishna Rawool* https://www.linkedin.com/in/balkrishnarawool/* Vector API, project Panama22:44 Christos Kotselidis, Michalis Papadimitriou* https://www.linkedin.com/in/michalis-papadimitriou/* https://www.linkedin.com/in/kotselidis/* https://www.tornadovm.org/* https://www.tornadovm.org/gpullama3* https://github.com/beehive-lab/TornadoVM* TornadoVM status update, Java on GPU* How TornadoVM relates to Project Babylon and Project Panama33:42 Outro

Java is a 30-year success story, made possible because its development consistently aligned with users' needs. In its early days, the platform required new features quickly, but over time, minimizing code breakage while carefully evolving the platform became essential. Critical junctures along that path included the introduction of modules and the current strive toward integrity by default. Nicolai Parlog talks to Mark Reinhold, Chief Architect of the Java Platform, who brings nearly three decades of experience shaping Java's evolution.

OpenJDK projects such as Amber and Valhalla are renowned for their careful and methodical approach to designing and introducing new features to the Java platform. In this episode, Nicolai Parlog is joined by Brian Goetz, Java Language Architect at Oracle and lead of both Project Amber and Project Valhalla. Brian shares insights and updates on these influential initiatives as they discuss Amber's upcoming feature arc, Valhalla's plans for null-restriction, and more.

Jim Grisanzio from Java Developer Relations talks with Venkat Subramaniam who was recognized with the Java Community Lifetime Achievement honors by Oracle's Sharat Chander at Devoxx UK in May 2024. Venkat is a Java Champion, author, speaker, founder of Agile Developer, co-founder of the dev2next conference, and teacher at the University of Houston. In this conversation, which is part of an ongoing series honoring Java pioneers, Venkat expresses profound humility about his accomplishments and credits industry giants and his passion for learning and sharing technical knowledge. He reflects on leaving his own company years ago to focus on teaching and technology, writing books like Cruising Along with Java, and speaking at over 45 conferences and 30 Java User Groups — every single year! Venkat has one of the most impressive global speaking schedules of anyone in the Java community. Venkat praises Java User Group leaders as “unsung heroes” for their organizational efforts and highlights Java 25's evolving features like structured concurrency, scoped values, pattern matching, and the instance main method, which helps simplify the learning process for new developers. Venkat also cites Java's agile six-month release cycle, which helps improve the smooth evolution of Java, increases developer engagement, and makes Java more suitable for today's rapidly expanding technology markets. Emphasizing teaching as reciprocal learning, Venkat advises students to engage mentors and senior developers to collaborate with juniors to help welcome into the community. He stresses that knowledge grows when shared. His mantra? Teaching fuels learning and he lives that ethic every day as he interacts with thousands of developers around the world.

Jim Grisanzio from Java Developer Relations talks with Bruno Souza, who is a Java Champion, leader of the SouJava User Group in Brazil, and a member of the JCP Executive Committee. Bruno received the first Java Community Lifetime Achievement recognition in October 2022 at JavaOne in Las Vegas. "I was totally surprised! I was jumping up and down! I was so honored! It's an honor to be a member of that group." he said. Bruno Souza is known as the "JavaMan" from Brazil and that nickname started back at Sun when Java was announced and Bruno started evangelizing the technology. Bruno's message to the community was "Open Standards and Open Source" as he began his community building efforts around Java. He continually brought to Brazil FOSS and Standards experts for community discussions, and he advocated for a standards-based Open Source implementation of Java that would pass the TCK. Bruno left Sun and then returned, and he also joined the JCP (Java Community Process). Now all these years later we have OpenJDK, and open JCP, and hundreds of independent JUGs that can participate in community building and also Java development. "Maybe my greatest pride, I think, is the idea of the Java User Groups community," Bruno says. "We have OpenJDK for development and the JCP for standards, but for me the real Java community is the Java User Groups! These are all volunteers who meet and help others participate and learn." Bruno in recent years has been talking a lot about building reputation and career by embracing the open-source lifestyle — writing code in Java, contributing to Open Source, and helping build the community itself. Since our work lives in public mailing lists and open-source code repositories, we earn credibility by being visible, contributing, engaging the community, and helping others get involve as well, Bruno says.  Bruno advises that career is a long-term project: "The more you work on it, the more you grow, the more results you have. So, the sooner you start the better. This is not a sprint! This takes time." Getting back to Java itself, Bruno, like most Java developers, prefers the 6-month release cadence over the older system of multi-year development and release cycles. There is a constant flow of technology now which allows for more interactions between the Oracle engineers and engineers in the community. "Everything you see today in Java is possible because of the 6-month release process. I just loved it when the guys did that! I think it's amazing! The fact that we now have two releases per year changed Java. I think we're positioning Java to be even stronger in the years to come. I'm very excited about the whole thing," Bruno says. Throughout this conversation Bruno provides a wonderful history of Java since he's been involved from the very beginning! "People don't remember that Java was a community from the very beginning!" Bruno says. “We were able to look at the source code from the very beginning and that allowed us to build the community from the very beginning with lots of other companies joining." And then the JCP was created to allow Sun and the community to discuss the standardization of Java. And then OpenJDK was a huge step because now Java would be everywhere with Oracle leading and building the community. "Java is more participative today under Oracle than during the Sun times." "Java + Open Source + Community: That's what grows our career. That's what grows Java too!" — Bruno Souza Bruno Souza https://x.com/brjavaman  https://x.com/SouJava  Duke's Corner Java Podcast  https://dukescorner.libsyn.com  Jim Grisanzio  https://x.com/jimgris  https://jimgrisanzio.wordpress.com https://www.linkedin.com/in/jimgris/ 

Jim Grisanzio from Java Developer Relations talks with Trisha Gee, an author, a Java Champion, and a Developer Advocate at Gradle. In February 2025 at Jfokus in Stockholm Trisha received the Java Community Lifetime Achievement Award from Sharat Chander from Oracle Java Developer Relations. Trisha has been a Java developer for 25 years, and since 2011 she's been actively blogging, presenting technical sessions at conferences, and evangelizing Java globally. Recently, Trisha has moved from a traditional developer advocate role to more of a facilitator of developer advocacy internally at her company as well as externally. She works with engineering teams, marketing, teams, and sales teams to ensure the voice of the developer resonates throughout the organization and the community. Trisha is always evolving, she's constantly growing. In this conversation we talk about the JVM, the six month Java release cycle, writing code, the unique features that make Java special as a technology and as a community, Generative AI, design patterns, understanding requirements, asking questions, problem solving, edge cases, documentation, testing, open source, standards, advice for students, and teaching her 9-year old how to code in Java. Trisha is fascinated with the entire development life cycle of software projects and especially the skills developers need now for working with AI. “It feels like a very personal thing from him … he's such a huge powerhouse in the community. Obviously, he cares about the technology, but he understands that the technology isn't enough. It is about individuals stepping up but not just doing stuff for themselves but doing stuff to enable other people, to empower other people. It's the community that makes it a great place to be, and Shar is such a huge champion of that. He makes you feel really appreciated for making the effort to help others and to be involved in the community.” — Trisha Gee commenting about receiving the Java Community Lifetime Achievement recognition from Sharat Chander at Oracle.

Jim Grisanzio from Java Developer Relations talks with Cay Horstmann, a professor, author, and Java Champion. In April in Cologne, Germany at JCON Cay received the Java Community Lifetime Achievement recognition from Sharat Chander on the Oracle Java Developer Relations Team. This conversation covers the evolution of Java, the constant polishing of the library, the upcoming Java 25 release, the six-month release cycle, improvements in the Java language to make the technology more beginner friendly, teaching methodologies, conferences vs unconferences, and also timeless task-driven learning methods for students and developers to keep their skills sharp. Also, Cay has been writing books about Java for decades and years ago he was instrumental in initially getting Java integrated into the curriculum for the computer science AP exam in the United States. “One of the reasons why Java is still so vibrant 30 years in is that there is a constant stream of low-level innovation going on. It's pretty amazing.” Cay Horstmann https://horstmann.com/ Duke's Corner Java Podcast https://dukescorner.libsyn.com Jim Grisanzio https://x.com/jimgris https://jimgrisanzio.wordpress.com https://www.linkedin.com/in/jimgris/

Jim Grisanzio from Java Developer Relations talks with Nate Schutta, an author, a teacher, a software architect, and Java Champion. Nate lives in the United States and teaches computer science to university students. He loves teaching and he loves learning, and he specializes in exploring the big picture of complicated systems in his career as a software architect. The conversation covers the Java community, the value for developers if they contribute to Java User Groups (JUGs), the benefits and some possible drawbacks of AI, and the engineering feat that is the Java Virtual Machine (JVM). Nate has a passion for learning and here's his advice for young developers and engineering students. “The fundamentals can't be skipped! And they take time to learn! You just have to put in those hours to understand the basics, and then you can graduate to the more complicated stuff.” Nate tripped over Java a bit in school and joined his first Java project right in his first job. Once he heard about this new Java project, he said: “Heck, yeah! I want in on that!” Nate Schutta https://x.com/ntschutta https://bsky.app/profile/nts.bsky.social Duke's Corner Java Podcast https://dukescorner.libsyn.com Jim Grisanzio https://x.com/jimgris https://jimgrisanzio.wordpress.com   

The Java runtime offers a host of guarantees like memory safety, type safety, encapsulation, and many more. What makes these aspirations actual guarantees is a property called “integrity”. But there are a few mechanisms in Java that allow undermining integrity - some for good, some for less good reasons. Integrity by default states that all such operations need to be disabled by default. Today we discuss why that is so important, what the progress toward this goal has been, and what Java developers need to know to keep their applications going. Nicolai Parlog talks to Ron Pressler, who is Java Architect at Oracle and, among other things, lead of Project Loom.

In this special in-person episode, Sanne Grinovero shares the story of Java's evolution from his unique perspective as a long-time open-source contributor. He shares his 16-year career journey at Red Hat, highlighting his amazing work on key projects like Hibernate, Infinispan, and especially the creation of Quarkus. His career trajectory, from a student who initially disliked Java's complexity to a leading figure in its modernization, shows the transformative power of open source.A key part of the conversation focuses on how technical challenges spark innovation. Sanne explains how the task of making the popular Hibernate framework compatible with GraalVM's limitations led directly to the birth of Quarkus.

The Stable Values API is a preview feature in Java 25 that allows developers to define immutable objects that are initialized at most once. It combines the flexibility of lazy initialization with the performance advantages of final fields. In this episode, Ana hosts Per Minborg, a member of the Java Core Library team at Oracle and co-author of JEP 502 on Stable Values. Per explains the concept behind Stable Values and how this approach addresses the drawbacks of eager initialization in Java. By deferring the creation of expensive resources until they are actually needed, Stable Values contribute to more efficient application startup. He also discusses the design process and specifics of the API, highlighting its benefits in multi-threaded environments—particularly its ability to ensure thread-safe, at-most-once initialization without the need for complex synchronization mechanisms.

OpenJDK's Project Leyden aims to improve the startup and warmup time of Java applications, for now by shifting computation from those phases to the applications' build time. Java 24 ships with ahead-of-time class loading and linking, which is the first step in that direction. In this episode, we learn about that as well as about Leyden's approach to reach its goals and some features that are available in its early access build plus some that aren't. Nicolai Parlog discusses with Dan Heidinga, who is JVM Runtime Architect at Oracle and, among other things, member of projects Leyden and Valhalla.

Java leads by example regarding documentation: JavaDoc inspires trust in developers through its transparency on each Java API functionality, and the javadoc tool helps developers generate equally great documentation for their APIs and libraries. In this episode, Ana hosts Jonathan Gibbons, core contributor and maintainer of JDK tools, to discuss JavaDoc/javadoc developments, focusing on markdown in JavaDoc documentation comments. Given the importance of having code that is as easy to understand as it is functional, Jonathan dives into significant changes in Java's documentation component and associated tools, how JavaDoc is maintained, code documentation practices, and more.

Azul, the only company 100% focused on Java, has announced that the integrated risk management practices for its OpenJDK solutions fully support the stability, resilience and integrity requirements in meeting the European Union's Digital Operational Resilience Act (DORA) provisions. With the upcoming DORA enforcement deadline of January 17, 2025, quickly approaching, thousands of EU financial organisations and companies around the world with business in the EU must act quickly to ensure their IT infrastructure meets stringent new operational resilience standards that potentially require significant time investments to fulfill. DORA's primary goal is to enhance the digital resilience of financial entities, mitigate risks associated with Information and Communications Technology (ICT) risks and ensure that financial entities can withstand, respond to, and recover from all types of ICT-related disruption.This includes risks from ICT service providers that deliver digital and data services through ICT systems to internal or external users; it also includes hardware services and technical support via software updates. Java is the programming language of choice for the Financial Services industry. According to the 2022 FINOS State of Open Source in Financial Services report, 51% of the code within the financial services data set is written in Java. Navigating the Complexities of Digital Operational Resilience Azul's comprehensive long-term support (LTS) Java versions ensure stability and ongoing security updates - including updates for older Java versions like versions 6 and 7 - crucial for maintaining operational resilience under regulatory scrutiny. The company's security features, comprehensive testing and compatibility with modern architectures and cloud environments provide a secure and scalable Java platform. With a proven track record in stability, reliability, and security, Azul's Java solutions help customers meet the requirements of DORA. The DORA regulation represents a significant shift in how financial institutions must approach their digital operational resilience, with non-compliance resulting in corporate fines of up to 2% of annual turnover and potential fines for individuals up to €1,000,000. This extensive regulation affects not only EU financial entities but also global organisations with EU operations or business relationships and third-party service providers. Azul's DORA Assessment Results According to Crucyble, the information security consulting firm that evaluated and assessed Azul's DORA-related risk management practices: "Azul has made considerable efforts to comply with the Digital Operational Resilience Act (DORA) EU by implementing a robust governance framework, risk management protocols, incident response capabilities, and third-party risk management strategies. Through continuous monitoring, regular testing, including penetration tests, and comprehensive plans for ICT resilience and recovery, Azul demonstrates a strong commitment to ensuring operational continuity and resilience. "The company is actively addressing the requirements of DORA EU to support its financial customers in maintaining operational integrity and security. Azul's proactive stance ensures it is well-equipped to meet the evolving challenges of ICT risk management and digital operational resilience, reinforcing its readiness to support customers in complying with the DORA EU framework." Azul's offering includes: Fully supported, OpenJDK distributions (Azul Platform Core and Azul Platform Prime) that ensure timely security updates and patches. Stabilised security-only updates across all Java versions, operating systems and architectures. Continuous vulnerability monitoring and accelerated remediation response time with Azul Intelligence Cloud. Expert guidance and support for migration from unsupported OpenJDK distributions.

Since Oracle changed the licensing for Java in January 2023, there has been growing demand from customers looking to switch away due to extra costs being imposed. Last summer Azul conducted a study of Oracle Java customers with 86% saying they are migrating all or some of their use and 47% expressed a desire to use an open-source distribution like OpenJDK.  Despite this appetite for change there are still somewhat cliched perceptions about moving to an open source-based JDK, even though the OpenJDK is based on the same source code as Oracle Java. There are some concerns about “better the devil you know” and a preconception that migration is difficult, but as the study showed 75% completed their migration to the OpenJDK within 12 months. To learn more about this I spoke to Scott Sellers, co-founder and CEO of Azul. Scott talks about his background, what Azul does, Azul's benchmarking tests, Azul's new Java Performance Engineering Lab and more.  More about Scott Sellers: With more than 30 years of successful leadership in building high technology companies and delivering advanced products to market, Scott provides the overall strategic leadership and visionary direction for Azul Systems.  Scott has a consistent proven track record of vision, leadership, and success in enterprise, consumer and scientific markets. Prior to co-founding Azul Systems, Scott founded 3dfx Interactive, a graphics processor company that pioneered the 3D graphics market for personal computers and game consoles. Scott served at 3dfx as Vice President of Engineering, CTO and as a member of the board of directors and delivered 7 award-winning products and developed 14 different graphics processors. After a successful initial public offering, 3dfx was later acquired by NVIDIA Corporation.  Prior to 3dfx, Scott was a CPU systems architect at Pellucid, later acquired by MediaVision. Before Pellucid, Scott was a member of the technical staff at Silicon Graphics where he designed high-performance workstations. Scott graduated from Princeton University with a bachelor of science, earning magna cum laude and Phi Beta Kappa honors. Scott has been granted 8 patents in high performance graphics and computing and is a regularly invited keynote speaker at industry conferences.
