David Delabassee 59 Episodes Sep 24, 2026

Inside Java is a podcast for Java Developers brought to you directly from the people that make Java at Oracle. We'll discuss the language, the JVM, OpenJDK, platform security, innovation projects like Loom and Panama, and everything in between.

"Security in Java" [AtA]
"Security in Java" [AtA] Sep 24, 2026 33:17 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 ess

"AOT Caching - Netflix' Practice vs OpenJDK's Theory" [I/O] Sep 17, 2026 01:11:17 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
"Declassifying the Java 27 Release!" [IJN]
"Declassifying the Java 27 Release!" [IJN] Sep 10, 2026 15:37 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]
"Operator Overloading with Type Classes" [AtA] Aug 27, 2026 41:39 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 annoyi

"JSON API, Valhalla Progress, LTS ❤️ PQC" [IJN]
"JSON API, Valhalla Progress, LTS ❤️ PQC" [IJN] Aug 15, 2026 10:28 JEP 540 proposes to incubate a simple JSON API and is currently proposed to target JDK 28. The pull request for Project Valhalla's JEPs 401 and 539 were merged and value types are available as a preview feature in the latest JDK 28 early-access builds. Oracle plans to backport post-quantum cryptography to Oracle JDKs with LTS (25, 21, 17, 11, and 8) and move Java to monthly security updated (curre
"Embracing Virtual Threads with Helidon" [I/O]
"Embracing Virtual Threads with Helidon" [I/O] Aug 6, 2026 14:05 Helidon 4.4 was released in April 2026 and stands out from other web frameworks by embracing new Java features as early as possible, particularly virtual threads and ahead-of-time computation. It is also aiming to become an OpenJDK project in the coming months. In this "Input/Output" episode of the Inside Java Podcast, recorded during JavaOne 2026, Nicolai Parlog talks to Joe Di Pol, Lead Principa
"JIT Compiler From the Ground Up" [AtA]
"JIT Compiler From the Ground Up" [AtA] Jul 30, 2026 45:53 While Java programs are deployed as bytecode, performance-relevant code will be compiled, at run time, to machine code whose performance rivals that of any other platform. In the HotSpot JVM, this is the job of the just-in-time compilers C1 and C2 and between speculation and traps, inlining and constant folding, escape analysis and scalar replacement (and many more), they apply a number of heurist
"AI Solutions with Spring AI 2.0 and Java" [I/O]
"AI Solutions with Spring AI 2.0 and Java" [I/O] Jul 23, 2026 19:36 Spring AI 2.0 released in June 2026 and is one of several projects ensuring Java's continued strength in enterprise AI development. Here are some tips on deterministic agents, MCP servers and skills, prompt engineering, and where Java's richness for AI solutions stems from. In this "Input/Output" episode of the Inside Java Podcast, recorded during JavaOne 2026, Lize Raes talks to Dan Vega, Spring
"JDK 27 + Valhalla, Now! + Hackathon" [IJN]
"JDK 27 + Valhalla, Now! + Hackathon" [IJN] Jul 19, 2026 10:03 JDK 27 entered Ramp-Down-Phase 1 in early June, so we can go over its features. Valhalla's first JDK Enhancement Proposal (401) will likely be part of JDK 28. Show off your Java ideas in the "Modern Java in the Wild" hackathon. There are two interesting articles for those who want to dive deeper into AOT with agents or into using GPU tensor cores from Java. Links: JDK 27 JEP list: https://openjdk
"Scripting JS and Python with Project Detroit" with Mikael Vidstedt [AtA]
"Scripting JS and Python with Project Detroit" with Mikael Vidstedt [AtA] Jul 9, 2026 16:26 OpenJDK recently resurrected Project Detroit, an effort to ease Java's interoperability with Python and JavaScript. Interestingly, while both integrations will work through the _java.scripting_ API, there are still differences between them. On top of that, the JavaScript integration needs to explain how it related to the removal of Nashorn in JDK 16. In this "Ask the Architect" episode of the Insi
"How JEPs Drive Java's Evolution" with Alex Buckley [AtA]
"How JEPs Drive Java's Evolution" with Alex Buckley [AtA] Jun 25, 2026 56:39 JDK Enhancement Proposals are OpenJDK's vehicle for documenting and communicating substantial changes of the Java language, its APIs, and the runtime but also the JDK project itself, for example when it comes to development processes. Their well-defined structure and the immense care that goes into writing them make them eminently readable and understanding them well is essential to understanding
