Is your Java application actually secure, or does it just look that way? In this episode of the Foojay Podcast, Frank is joined by Steve Poole and David Welch, both from HeroDevs, to dig deep into the state of Java security in 2025 and beyond.Steve introduces the concept of zombie dependencies: end-of-life libraries that appear safely dormant but are quietly accumulating vulnerabilities waiting to bite you. David, a co-chair of the CVE Automation Working Group, explains what a CVE actually is, how the identification and disclosure process works in practice, and why AI tools like Mythos are dramatically accelerating the pace at which new vulnerabilities are found — on both sides of the wall.Together they cover how CVEs in the Java runtime are handled through coordinated disclosure, why Maven Central is safer than most ecosystems but not a silver bullet, and what insurance companies are starting to demand from organizations that haven't cleaned up their dependency trees. They also discuss practical steps any Java developer can take today, from generating an SBOM and running Snyk or Trivy, to adopting OpenRewrite and Renovate in your pipelines, and why vibe coding with AI tools may be quietly making your security posture worse if you are not reviewing the dependency choices being made for you.A candid, occasionally alarming, and ultimately optimistic conversation about a problem the Java community is well-positioned to lead on.Steve PooleLinkedInFoojay Author profileCrossing the River Styx: Spring Boot 3.5 and the Zombie Dependency ProblemWhy Java Developers Over-Trust AI SuggestionsDavid WelchLinkedInContent00:00 Introduction of topics and guests04:00 What are Zombie dependencies?05:36 What are CVEs?11:39 How Mythos and other AI tools are influencing the CVE reporting process16:53 How CVEs in the Java runtime are handled21:30 How the industry is looking at the increased security threats30:17 Developers need to make better decisions "the first time" and use the right tools31:42 Keep your OS, JVM, and dependencies up-to-date!

Foojay.io, the website for the Friends of OpenJDK, is turning six years old. To celebrate, Frank Delporte headed to JCON in Cologne, Germany, and sat down with twelve members of the Java community to talk about what Foojay means to them, what they learn from each other, and how the community is evolving.Foojay is more than a blog. It is a Mastodon server, a Slack community, the Disco API, a book on sustainability, a podcast, and now an education catalog. Six years in, it is still growing, still community-driven, and still very much a place where anyone who works with Java is welcome.00:00 Introduction02:16 Sharat Chandarhttps://www.linkedin.com/in/sharatchander/Java community and historyWhat you can learn from conferences and articles05:37 Markus Westergrenhttps://www.linkedin.com/in/markuswestergren/https://foojay.io/sustainability-for-java-developers/https://foojay.io/today/join-slack-com-t-foojay-signup/Book "Sustainability for Java Developers"How to "sustain yourself" in this strange-AI-changing-world09:46 Iryna Dohndorfhttps://www.linkedin.com/in/iryna-dohndorf/https://foojay.io/today/author/iryna-dohndorf/Mentoring about sustainability as a developer + groundness + robustness skillsHigh performance without crushing your soul13:59 René Schwietzkehttps://www.linkedin.com/in/reneschwietzke/https://foojay.io/today/the-curious-case-of-different-runtimes-with-different-training-data-jit/Diving deep into the runtime, JITWatchAbout the broad mix of topics handled on Foojay18:28 Gerrit Grunwaldhttps://www.linkedin.com/in/gerritgrunwald/ https://foojay.io/today/author/gerrit-grunwald/https://foojay.io/today/disco-api-helping-you-to-find-any-openjdk-distribution/https://sdkman.io/The Disco API, the source with all the available OpenJDK distributions, is used by SDKMAN, Gradle, and many other toolsAbout the many distributions that are available, even ones that are mainly (and only) used in Asia27:45 Catherine Edelveishttps://foojay.io/today/author/catherine-edelveis/https://www.youtube.com/watch?v=Ytdo8OGEYFIhttps://foojay.io/today/which-java-runtime-should-you-use-in-production-comparing-openjdk-distributions/Reducing Docker sizes improves security and performanceMany distributors provide builds of OpenJDK31:16 Jago de Vreedehttps://foojay.io/today/author/jago-de-vreede/About the Java community and the place of Foojay in it.

In this episode of the Foojay Podcast, we're bringing you something special: a full batch of hallway-track conversations recorded live at VoxxedDays Amsterdam.Fifteen guests, one conference, and one theme that kept coming back, whether we planned it or not: Java has grown up quietly, steadily, and in ways that still surprise people who haven't looked lately. We talked about migrating between versions, new features in the latest Java releases, authorization done right, AI-assisted coding, cryptography, containers, open-source contributions, GDPR data experiments, and, yes, the things people hate about Java but secretly love.I spoke with Ko Turk, who organized this very conference, Johannes Bechberger, Lutske de Leeuw, Aicha Laafia, Marit van Dijk, Adele Carpenter, Patrick Baumgartner, Sohan Maheshwar, Jeroen Egelmeers, Erwin Manders, Alexander Shopov, Maarten Verburg, Arjan Tijms, Joost Kaan, and Stephan Janssen.That's a lot of people. That's a lot of opinions. And somehow, they mostly agree: update your JDK, read your code, and please talk to your actual users.Content00:00 Introduction00:30 Ko Turkhttps://www.linkedin.com/in/ko-turk-b271b929/Organizer of VoxxedDays AmsterdamMigrating between Java versions02:25 Johannes Bechbergerhttps://www.linkedin.com/in/johannes-bechberger/Java is boring, and that's why it's brilliantJava 26 test it, but not in productionJFR improvements in the latest versions06:28 Lutske de Leeuwhttps://www.linkedin.com/in/lutske/Volunteer at the conferenceJava is boring, and that's why it's brilliantJava 5 till 26 evolutions10:35 Aicha Laafiahttps://www.linkedin.com/in/aicha-laafia-0266a6126/Lambda stream gatherers in Java 25Simpler and more fun codeUpdate your JDK!16:16 Marit van Dijkhttps://www.linkedin.com/in/maritvandijk/Fun in coding, write Java the playful wayJava evolutions and how writing code has evolvedImportance of code reading with AI-assisted coding22:04 Adele Carpenterhttps://www.linkedin.com/in/adele-carpenter-a988623a/The things I hate about Java, but actually love it27:37 Patrick Baumgartnerhttps://www.linkedin.com/in/patbaumgartner/Organizing VoxxedDays ZurichSpring Boot optimizationUsing Buildpacks to create better containers35:02 Sohan Maheshwarhttps://www.linkedin.com/in/sohanmaheshwar/Authorization, the good wayJWT is a bad idea38:34 Jeroen Egelmeershttps://www.linkedin.com/in/jegelmeers/https://craftingaiprompts.org/documentation/se-framework/craft-frameworkAI, prompt engineering, agentic programmingThe CRAFT Framework: Orchestrating Agentic FlowThe importance of interacting with your end-users43:32 Erwin Mandershttps://www.linkedin.com/in/erwinman/Cryptography, digital signatures, and securing data and messagesComparing Kotlin and Java45:12 Alexander Shopovhttps://www.linkedin.com/in/alshopov/Developer at UberComparing different languages: Java, Python, GoHow Java is modernizing by learning from other languages49:18 Maarten Verburghttps://www.linkedin.com/in/maartenverburg/Using your own GDPR data for fun experimentsComparing early Java with the current statusJava Streams the most important change52:35 Arjan Tijmshttps://www.linkedin.com/in/arjantijms/https://omnifi
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?<a href="https://openjdk.org/jeps/836110
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
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!)<a href="https://webtec
For this episode of the Foojay Podcast, we invited the author of three recent posts published on Foojay. And he brought a colleague to get even more expert knowledge in this podcast! We talk about Quarkus, how it is "cloud-native", how it compares to other frameworks, the advantages for developers and managers, etc. We also discussed nano businesses and how they can serve as a model for paying creators of digital content, thanks to x402 and ERC-8004.

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.00:00 Introduction of topic and guests01:33 Stephan Janssenhttps://www.linkedin.com/in/stephanjanssen/ Devoxx Organizer07:03 Martin Smelthttps://www.linkedin.com/in/martin-paul-smelt-8b699a8/JFall Organizer 13:27 Brian Vermeerhttps://www.linkedin.com/in/brianvermeer/JFall Organizer and speakerTips for speakers, writing a CFPJoin a JUG! 21:02 Annelore Eggerhttps://www.linkedin.com/in/anneloredev/How to become a speaker27:43 Daniël Floorhttps://www.linkedin.com/in/dani%C3%ABl-floor-266652208/Taking the first steps into public speakingFinding your speaking topic31:28 Berwout de Vries Robleshttps://www.linkedin.com/in/berwout-de-vries-robles/Tips for speakersPropose a talk to speak at a JUG37:08 Susanne Pietersehttps://www.linkedin.com/in/susannepieterse/Learning at conferences, RAG, and other topicsMeeting and talking to the presenters and specialists at a conferenceCO-organizer of ML Con and DevOpsCon in Amsterdamhttps://mlconference.ai/https://devopscon.io/amsterdam/41:20 Conclusion
