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 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.

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. This journey tells the bigger story of how Java adapted for cloud-native development, ensuring it continues to be a top choice for developers seeking high performance and a great developer experience.  Timestamps:(00:00:00) Trailer & Intro(00:02:16) Career Turning Points(00:04:52) Winning an Innovation Award(00:06:35) Java Heroes(00:08:04) Working as a Consultant(00:09:56) Taking a Massive Pay Cut to Work on Open Source(00:10:59) Contributing to Big Open Source as a Youngster(00:12:53) State of Hibernate Project(00:15:15) Spring Boot(00:16:54) Making Hibernate Work on GraalVM(00:21:05) GraalVM Limitations for Running Hibernate(00:26:09) Java for Cloud Native Application(00:28:04) Quarkus vs Spring Boot(00:33:21) JRebel & Quarkus(00:34:35) Java vs New Programming Languages(00:39:22) The ORM Dilemma(00:42:38) Some Hibernate Design Pattern Tips(00:46:40) Getting Paid Working on Open Source(00:48:41) Hibernate License Change(00:51:05) Intellectual Property & Meaningful Contributions(00:52:52) AI Usage & Copyright in Open Source(00:55:21) Biggest Challenge Working in a Big Open Source(00:56:08) Politics in Open Source(00:58:32) Security Risks in Open Source(01:02:25) Donating Hibernate to Commonhaus Foundation(01:04:49) The Future of Red Hat(01:06:39) 3 Tech Lead Wisdom_____Sanne Grinovero's BioSanne Grinovero has been a member of the Hibernate team for 10 years; today he leads this project in his role of Sr. Principal Software Engineer at Red Hat, while also working on Quarkus as a founding R&D engineer.Deeply interested in solving performance and concurrency challenges around data access, scalability, and exploring integration with new storage technologies, distributed systems and search engines.Working on Hibernate features led him to contribute to related open source technologies; most notably to Apache Lucene and Elasticsearch, Infinispan and JGroups, ANTLR, WildFly, various JDBC drivers, the OpenJDK and more recently getting interested in GraalVM.After being challenged to reduce memory consumption and improve bootstrap times of Hibernate, Sanne worked as part of a small R&D team at Red Hat on some ideas which have evolved into what is known today as Quarkus.Follow Sanne:LinkedIn – linkedin.com/in/sannegrinoveroTwitter – twitter.com/SanneGrinoveroGitHub – github.com/sanneLike this episode?Show notes & transcript: techleadjournal.dev/episodes/220.Follow @techleadjournal on LinkedIn, Twitter, and Instagram.Buy me a coffee or become a patron.

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.

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. DORA Compliance Considerations for Use of Java Apps and Java-based Infrastructure To support financial entit...

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.

The Foreign Function and Memory API will be finalised in JDK 22. This API helps you integrate native code within your Java program.  Using this new API you can efficiently invoke code outside the JVM, safely access memory not managed by the JVM, call native libraries and process native data without the brittleness and danger of JNI. Jorn Vernee, core contributor and maintainer of the FFM API, is Ana's guest during this episode. Jorn explains what is the Foreign Memory Access API, its goals and the iterations that this API went through. Jorn also shares a few examples of Java libraries that already adopted the FFM API, the performance improvements they observed. He also explains how you can use this new API to integrate a native library within your own Java code.
