    Java 26 Is Here: What's New, What's Gone, and Why It Matters in 2026 (#92)
    Mar 14 2026
    Welcome to another episode of the Foojay Podcast! In this episode, we're talking about Java 26, released on March 17 in the year 26. Again, right on schedule with Java's six-month release cadence.Now, Java 26 is not a Long Term Support (LTS) release; that was Java 25. But don't let that fool you into thinking there's nothing interesting here. This release brings ten JDK Enhancement Proposals (JEPs). They cover everything from performance improvements to long-overdue cleanups. Of those ten JEPS, five are new features, and we also get five preview/incubator features.GuestsSimon Ritterhttps://www.linkedin.com/in/siritter/Loïc Mathieuhttps://www.linkedin.com/in/lo%C3%AFc-mathieu-475b144/Content00:00 Introduction of topic and guests01:35 Differences between Long and Short Term Support05:10 Which Java versions are used by companieshttps://foojay.io/today/foojay-podcast-90-highlights-of-the-java-features-between-lts-21-and-25/07:54 Internal changes and improvements in release 26, highlighting UUIDv7 supporthttps://foojay.io/today/java-26-whats-new/12:02 JEP 500: Prepare to Make Final Mean Final13:24 JEP 526: Lazy Constants (Second Preview)16:12 JEP 517: HTTP/3 for the HTTP Client APIhttps://en.wikipedia.org/wiki/HTTP/3https://en.wikipedia.org/wiki/QUIC18:48 JEP 504: Remove the Applet API20:52 JEP 524: PEM Encodings of Cryptographic Objects (Second Preview)21:59 JEP 516: Ahead-of-Time Object Caching with Any GChttps://openjdk.org/projects/leyden/https://docs.azul.com/prime/analyzing-tuning-warmuphttps://foojay.io/today/faster-java-warmup-crac-versus-readynow/25:30 JEP 522: G1 GC: Improve Throughput by Reducing SynchronizationTrash Talk - Exploring the JVM memory management by Gerrit Grunwald28:04 JEP 525: Structured Concurrency (Sixth Preview)https://openjdk.org/projects/loom/31:09 JEP 529: Vector API (Eleventh Incubator)https://openjdk.org/projects/panama/https://openjdk.org/projects/valhalla/34:59 When do JEPs get selected to be included in a releasehttps://openjdk.org/projects/jdk/26/https://openjdk.org/projects/jdk/27/38:03 JEP 530: Primitive Types in Patterns, instanceof, and switch (Fourth Preview)https://openjdk.org/projects/amber/Java Puzzlers talk by Simon42:14 Do we need "Carrier Classes"?Amber mailing list: Data Oriented Programming, Beyond RecordsJVM Weekly newsletter by Artur Skowroński44:38 What changes does Java need for the AI world?JEP DRAFT 8361105: Code reflection (Incubator)https://openjdk.org/projects/babylon/https://www.tornadovm.org/47:53 Remarkable numeric facts about releases48:30 Conclusion

  • 25 Years of IntelliJ IDEA: The IDE That Grew Up With Java

    25 Years of IntelliJ IDEA: The IDE That Grew Up With Java
    Feb 28 2026
    In this Foojay Podcast, we're celebrating a major milestone in Java development history: 25 years of IntelliJ IDEA.Think about it: IntelliJ IDEA launched in 2000, and since then, it has become the go-to IDE for millions of Java developers worldwide. From its revolutionary code completion and refactoring tools to AI-powered features and the recent unified Community and Ultimate release, IntelliJ has shaped how we write Java, and keeps reinventing itself to stay ahead.For this episode, I'm joined by three people from the JetBrains team who know this story inside and out. Marit van Dijk, developer advocate and contributor to the Foojay community. Anton Arhipov, also a developer advocate at JetBrains. And Dmitry Jemerov, who has been part of the IntelliJ IDEA story for a very long time.GuestsMarit van Dijkhttps://foojay.io/today/author/marit-van-dijk/https://www.linkedin.com/in/maritvandijk/https://mastodon.social/@maritvandijkAnton Arhipovhttps://www.linkedin.com/in/antonarhipov/Dmitry Jemerovhttps://www.linkedin.com/in/dmitry-jemerov-3a59b43a5/LinksWebsiteDocumentationBlogYouTubeLinkedInBlueskyTwitterFoojay Podcast #81: Maven 4 – The Future of Java Build AutomationVideo: IntelliJ IDEA: The Documentary | [OFFICIAL TRAILER] | Coming March 5thIntroducing Mellum: JetBrains’ New LLM Built for Developers Mellum: Explore code-intelligent large language models for IDEs, AI assistants, research, and educationBirthday game websiteGame plugin in IntelliJ IDEAYou’re Invited to IntelliJ IDEA Conf 2025!The Unified IntelliJ IDEA: More Free Features, a Better Experience, Smoother FlowVideo: Troubleshooting Spring Boot Applications with the Spring DebuggerSpring Debugger pluginPlugin for IntelliJ IDEA (and other IDEs) created by Frank: Recent Projects OrganizedContent00:00 Introduction of topic and guests01:36 Now JetBrains started02:31 Licensed software in an open-source world06:37 Other JetBrains IDEs07:46 Why Kotlin was created08:50 The challenge of maintaining all the tools10:36 How the guests joined JetBrains14:03 IntelliJ versus IntelliJ IDEA, history of the name15:10 Most important ongoing changes in IDEs17:55 Unified distribution of IntelliJ IDEA and the history of the open-source version21:28 The number of people at JetBrains23:31 the "business model" behind Kotlin24:39 The impact of AI, LLM, Chat interfaces,...35:49 Upcoming evolutions in IntelliJ IDEA38:07 About shortcuts and the many features and plugins in IntelliJ IDEA46:36 Announcements: IntelliJ IDEA Conf 2026 and Documentary Trailer48:35 The IntelliJ IDEA Birthday Game49:24 Conclusions

  • From Java 21 to 25: The Features That Changed Everything (#90)

    From Java 21 to 25: The Features That Changed Everything (#90)
    Feb 14 2026
    Every six months, we get a new version of Java. Java 26 is just around the corner and will be released soon. But most companies stick to LTS (Long-Term Support) versions, which are maintained and receive security updates for many more years. Versions 8, 11, 17, 21, and 25 are such LTS versions. Hopefully, most of your systems are already on the latest versions and you are not stuck on 8 or earlier. As a reminder, 8 was released in 2014, so much has changed since then.If you are doubting moving from 21 to 25, or even from an earlier version to the latest LTS, this podcast is for you! Together with Jakob Jenkov, we discussed the most important changes, and this episode includes a few quotes from interviews recorded at conferences last year.GuestsJakob Jenkovhttps://www.linkedin.com/in/jakob-jenkov-4a3a8/Jonathan Vilahttps://www.linkedin.com/in/jonathanvila/Ryan Svihlahttps://www.linkedin.com/in/ryan-svihla-096752182/Mary Grygleskihttps://www.linkedin.com/in/mary-grygleski/Anton Arhipovhttps://www.linkedin.com/in/antonarhipov/Ronald Dehuysserhttps://www.linkedin.com/in/ronalddehuysser/Jonathan Ellishttps://www.linkedin.com/in/jbellis/Content00:00 Introduction of topic and guestTutorials by JakobPodcast #89: Quarkus and Agentic Commerce03:30 Bugfixes and performance improvements "under the hoods"Quote Jonathan Vila08:00 Java as a scripting languageQuote Ryan SvihlaCompact Source Files and Instance Main methodsLaunch Multi-File Source-Code Programshttps://www.jbang.dev/Quote Mary Grygleski15:03 GC ImprovementsGenerational ShenandoahTrash Talk - Exploring the JVM memory management by Gerrit GrunwaldWhat Should I Know About Garbage Collection as a Java Developer?19:44 Project Loom: Virtual Threads and Structured ConcurrencyQuote Anton Arhipov29:44 How Java evolves6-months release cycleHow incubator and preview features are used to get feedback from the communityLong-Term Support Short-Term Support versionsFoojay Podcast #28: Java 21 Has Arrived!Foojay Podcast #45: Welcome to Java 22Foojay Podcast #57: Welcome to OpenJDK (Java) 23Foojay Podcast #68: Welcome to OpenJDK (Java) 24Foojay Podcast #78: Welcome to OpenJDK 25!32:15 Project Leyden: Ahead-of-time featuresAhead-of-Time Command-Line ErgonomicsAhead-of-Time Method ProfilingAhead-of-Time Class Loading & Linking39:15 Project BabylonJava on CPU, GPU, FPGA?This is already possible with TornadoVMFoojay Podcast #82: OpenJDK Projects (Leyden, Babylon, Panama) and TornadoVM43:25 Class-File APIQuote Ronald DehuysserJavaFX In Action #22 with Matt Coley, diving into byte code and JARs with Recaf and JavaFX libraries49:20 Foreign Function and Memory APIThe FFM API: How OpenJDK Changed the Game for Native Interactions (And Made Pi4J Better!)jChampions Conference talk 'Foreign Function & Memory (FFM) API on Raspberry Pi'54:26 Vector APIQuote Jonathan Ellis + Ryan Svihla59:59 Removal of String templates01:00:26 Taking a look into the JVM of the future01:03:08 Conclusion

  • From Code to Stage: Organizing Conferences and Finding Your Voice as a Speaker (#88)

    From Code to Stage: Organizing Conferences and Finding Your Voice as a Speaker (#88)
    Dec 27 2025

    What turns a nervous first-timer into a confident conference speaker? Let's find out.

    This the last Foojay Podcast of 2025 and also the last one with interviews recorded at the Devoxx and JFall conferences. Maybe you're already thinking about your goals for 2026: organizing a meetup, submitting your first conference talk, or taking a bigger role in the Java community. If that sounds like you, this episode is for you.

    I talked with the people behind these conferences and developers at different stages of their speaking journey. At Devoxx, I spoke with Stephan Janssen, who has been organizing Devoxx for 20 years, Susanne Pieterse, about what makes conferences valuable for learning, and Daniël Floor, a developer just starting out with public speaking. At JFall, I caught up with organizers Martin Smelt and Brian Vermeer, Berwout de Vries Robles, who coaches new speakers, and Annelore Egger about her journey from developer to conference speaker.

    You'll hear practical advice about what makes a good CFP, why conference organizers actively want new speakers, and how the Java community is set up to help you get started. Whether you're thinking about submitting your first talk or curious about what goes into organizing a conference, there's something here for you.

  • The Human Side of Development: Career Growth, Staying Healthy, and Why People Matter More Than AI (#87)

    The Human Side of Development: Career Growth, Staying Healthy, and Why People Matter More Than AI (#87)
    Dec 20 2025

    What if work-life balance is a myth, and the real secret is just... life?

    In this Foojay Podcast we're stepping away from pure code and diving into something equally important: how we live our lives as developers. Because let's be honest, being a great programmer isn't just about mastering Java or the latest framework. It's about managing your career, your health, your family, and finding purpose in all of it.

    Four incredible guests are all tackling different pieces of this puzzle. First up, Bruno Souza, the Brazilian Java Man, is back to challenge our thinking about work-life balance and share his philosophy on taking control of your career. Then Patricia Lenten talks about the real challenges of hacking parenting while being an engineer, and how we can inspire the next generation of developers. Georgios Diamantopoulos brings the hard data on why sitting is literally killing us and what we can actually do about it. And finally, April Schuppel shares lessons from Apryse's journey through 15 acquisitions in five years—and why people, not AI, are still the most important part of building great products.

  • Agents, MCP, and Graph Databases: Java Developers Navigate the AI Revolution (#86)

    Agents, MCP, and Graph Databases: Java Developers Navigate the AI Revolution (#86)
    Dec 13 2025

    The AI revolution isn't replacing Java developers. No, it's forcing us to think harder.

    Welcome to another episode of the Foojay Podcast! Today, we're talking about AI and Java, how it's changing the way we work, what we need to watch out for, and why understanding what's really happening matters more than ever.

    I recorded interviews at Devoxx and JFall and spoke with people who build and use this technology every day.

    Marianne Hoornenborg opened my eyes to something important: every time an AI generates a token, there's a massive amount of computation happening behind the scenes.

    Viktor Gamov and Baruch Sadogursky did something really cool: they tested six different AI coding tools live on stage with the same task. The results were all over the place! But they found that the tools with access to good documentation performed much better.

    Stephen Chin showed me how graph databases can make AI responses more reliable by providing a solid source of truth rather than relying on vector search.

    Mario Fusco works on LangChain4J, a leading Java framework for AI. He explained that breaking down large tasks into smaller ones and using specialized agents can help reduce errors—hallucinations, as they're called.

    Jeroen Benckhuijsen and Martijn Dashorst shared their experiences working with enterprise Java. Even as frameworks are becoming lighter and we're running everything in containers, there are still complex problems that require real developer expertise.

    Maarten Mulders reminds us that AI is a tool, not a replacement—especially when you're solving problems no one has tackled before. You still need to know what you're doing.

    And finally, Simon Maple from Tessel discussed moving beyond vibe coding towards a more reliable, production-ready approach, using specifications to guide AI tools.
