   "Carrier Classes" [IJN]

   This episode presents Project Amber lead Brian Goetz's recent email "Data Oriented Programming, Beyond Records", wherein he describes plans to improve Java's data handling capabilities by introducing carrier classes, a generalization of records. Like them, carrier classes describe their state through a component list that defines the type's external API: accessors, a constructor, and matching deconstructor - this allows carrier classes to participate in pattern matching and reconstruction. Unlike records, the implementation of this API remains the developer's task although component fields…

   "Java's Plans for 2026" [IJN]

   In 2026, Java keeps evolving: Project Valhalla is gunning for merging its value types preview in the second half of this year; Babylon wants to incubate code reflection; Loom will probably finalize the structured concurrency API; Leyden plans to ship AOT code compilation; and Amber hopes to present JEPs on constant patterns and pattern assignments. And those are just the most progressed features - more are in the pipeline and discussed in this episode of the Inside Java Newscast.

   The New Inside Java Podcast

   Welcome to the new Inside Java Podcast. In this meta episode, Nicolai Parlog introduces you to the podcast's new structure with two shows under one umbrella: The long-form conversations you know become Ask the Architects episodes and they'll be accompanied by the Inside Java Newscast as a podcast.

   "Predictability or Innovation? Both!" with Georges Saab

   This Inside Java Podcast takes a meta approach. Instead of focusing on specific features, it explores the bigger picture: What are the right problems for Java to tackle? What are the current and future challenges for the Java platform? Why is predictability so important for Java, and what's driving the recent focus on learners and students? Nicolai Parlog discusses these topics with Georges Saab, Senior Vice President of the Java Platform Group and Chair of the OpenJDK Governing Board.

   "From Sumatra to Panama, from Babylon to Valhalla" with John Rose

   Java's development embraces the past as well as the future and after contributing to it for over 30 years, John Rose is intimately familiar with the process. In this episode he talks about feature design, the right amount of technical debt (which isn't actually zero), why Rice's theorem demands a mix of static and dynamic checks, how Project Sumatra eventually birthed Panama and Babylon, and more. In this episode, Nicolai interviews John Rose, Senior Architect of the Java Virtual Machine, who brings over 30 years of experience advancing the Java platform.

   "Security in Java" [AtA]

   Given how prevalent Java is on web servers throughout the internet, security in Java is of critical importance. There's the security of the JDK itself, of course, which is overseen by the OpenJDK Security Group, which you should report JDK vulnerabilities to. But there are also the algorithms and features Java offers applications that are built on top of it and the cryptographic road map is an essential part of that development process. In recent years, post-quantum encryption has made big splashes but Java now also supports PEM texts and is considering the adoption of Argon2. In this "Ask…

   "AOT Caching - Netflix' Practice vs OpenJDK's Theory" [I/O]

   Java projects that want to reduce their launch times need to look into Java's new ahead-of-time capabilities. A training run is used to populate a cache that, in production, allows the JVM to short-circuit many operations, like class loading and linking, profile gathering, and - probably soon - JIT compilation. To get the most out this feature, a good training run is essential. Netflix approach is pretty much the ideal one: use a canary deployment of a new version to collect training data and create the cache for the remaining deployments from that. But, from time scales to checkpointing,…

   "Declassifying the Java 27 Release!" [IJN]

   Java 27 is heading for release on September 15th. As with every release of the JDK there are a host of changes that will impact developers, from new features, to changes in behavior of existing features. In this episode of the Inside Java Newscast we will be "declassifying" all the developer impacting changes in Java 27.

   "Operator Overloading with Type Classes" [AtA]

   OpenJDK's Project Valhalla is improving Java's support for custom numerical types. That goes beyond value types and also encompasses explorations into operator support. While Java is extremely unlikely to ever allow arbitrary operator definitions, it may well support limited operator overloading, so custom value types could be added or multiplied with plus or multiplication signs instead of annoying method calls. In this "Ask the Architects" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Joe Darcy, Valhalla committer in the Java Platform Group at…
