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. 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.

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. See more podcasts here.

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.
