David Delabassee 59 Episodes Aug 20, 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.

"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
"Java *is* Memory Efficient" with Ron Pressler [AtA]
"Java *is* Memory Efficient" with Ron Pressler [AtA] May 28, 2026 35:02 Java's use of memory, often chided for being excessive, is actually a strength as it trades more memory use for fewer CPU cycles. Java can only make this tradeoff due to its moving garbage collectors, something more memory efficient platforms often cannot. But what's the point in leaving available memory on the table if using it makes your program run faster? Efficient use of that resource wouldn'
"Java Gets Post-Quantum TLS" [IJN]
"Java Gets Post-Quantum TLS" [IJN] May 18, 2026 04:53 With JDK 27 introducing hybrid key exchange schemes that combine ML-KEM with traditional ECDHE algorithms, Java applications can gain TLS-layer protection against the harvest-now, decrypt-later threat without rewriting business logic. In this episode of the Inside Java Newscast, Ana explains post-quantum hybrid key exchange for TLS 1.3 and demonstrates how a Java application can take advantage of
"Make Java Safer with Flexible Constructor Bodies" [IJN]
"Make Java Safer with Flexible Constructor Bodies" [IJN] May 5, 2026 07:16 Flexible constructor bodies were added to Java 25 with JEP 513. In this episode of the Inside Java Newscast Billy Korando will review the issues with how constructors used to work before Java 25, either forcing developers to write convoluted code, or in some cases undermining the safety and integrity of child classes. Billy will then cover how flexible constructor bodies address these issues and h
"Ask the Architects at JavaOne'26" [AtA]
"Ask the Architects at JavaOne'26" [AtA] Apr 23, 2026 58:08 In JavaOne 2026's closing session, audience members had the opportunity to ask the Java architects questions. They asked about the state of structured concurrency and Project Babylon, how Java is being developed and the role AI plays in that process, the architects' pet projects, and whether they would ever consider breaking backward compatibility, etc.  Make sure to check https://inside.java/podc
