this article shows an approach to extend the HAT programming model with an API for explicit tensor-core programming. Furthermore, it shows how to make this approach generic to be able to process computations expressed with the proposed HAT tensor core API on accelerators without explicit tensor instructions.

Java's use of memory, often chided for being excessive, is actually a strength as it trades more memory use for fewer CPU cycles, a tradeoff it can only make due to its moving garbage collectors.

"JFR simplifies troubleshooting and profiling by capturing detailed JVM event data—and with the JFR Streaming API, you can access those insights in real time. But what if you could go further and stream live JFR data straight into an AI system to enhance monitoring, accelerate troubleshooting, and even help prevent issues before they occur?

The following JEP is targeted to JDK 27: 538: PEM Encodings of Cryptographic Objects (Third Preview)

The Java programming language is evolving fast. In this talk, we’ll summarize many of the recent changes that have appeared as well as look ahead to directions and features that are in development and will appear in future editions.

New release of Java Platform Extension for VS Code

To give you a clearer view of the performance work happening across the Java platform, this article highlights a selection of notable performance related improvements in JDK 26, grouped into four major areas: JDK Libraries, Garbage Collectors, Compiler, and Runtime.

Details and reflections on how I’ve been using AI to approach OpenJDK development.

The following JEP is targeted to JDK 27: 523: Make G1 the Default Garbage Collector in All Environments

These tutorials describe how to build accessible JavaFX applications.

"Draw the Rest of the Owl: Leyden in Production and the Infrastructure Needed to Get It There." Learn how Netflix used Project Leyden to improve startup time of critical services and the software and SDLC they built to make that happen.

This Heads-Up is part of the regular communication sent to the projects involved; it announces that JDK 27 approaches rampdown and final field mutation warnings heads-up.

Primitive defaults are chosen so that they are (probably) represented by memory set to one or more bytes with all bits set to zero; we call these all-zero-bits values. We want “primitive-like” classes to have similar optimization opportunities, even if some classes will choose to nominate defaults values that are not all-zero-bits values. This document discusses possible semantics for such…

This Heads-Up is part of the regular communication sent to the projects involved; it covers thatJSON thread dumps now emit thread identifiers, thread counts, and the process identifier as numeric types.

Since JavaOne 2025, Java has moved from JDK 25, the latest LTS release, toward JDK 26, with major updates across the language, APIs, runtime, tooling, security, startup performance, and garbage collection. This talk reviews the most important changes from Java 21 through 25, then explores JDK 26 and its preview features, including primitive patterns, lazy constants, structured concurrency, PEM…

The following JEP is targeted to JDK 27: 531: Lazy Constants (Third Preview)

Caching is a first-class architectural concern in agentic systems. This talk breaks down how Java applications can layer internal, distributed, and semantic caches. We'll explore in-process caching with Caffeine for ultra-low-latency access, distributed caching with Redisson and Valkey for shared cache and semantic caching using Vector Similarity Search to reduce latency and cost while scaling…

This session highlights the progress of JEP 528, which brings core dump and minidump support to jcmd. The jcmd tool is widely used for monitoring and troubleshooting live HotSpot JVMs. With JEP 528, jcmd will also be able to diagnose crashed JVMs, creating a more consistent troubleshooting experience across both live and post-mortem environments.

This Heads-Up is part of the regular communication sent to the projects involved; it covers that JDK 27 EA Builds now include post-quantum hybrid key exchange for TLS 1.3.

This Heads-Up is part of the regular communication sent to the projects involved; it covers the warnings that JDK 26 emits when final fields are mutated through reflection.

This Heads-Up is part of the regular communication sent to the projects involved; it covers the removal of deprecated Java launcher options.

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…

Get a deep dive with live coding showing how to specify, allocate, and work with native memory and how to link and call native functions. We'll also demo how to use the automatic binding generator tool jextract to effortlessly generate Java bindings to the ONNX Runtime, the open standard for machine learning models. Whether you're an architect rethinking cross-platform integration or eager to…

Flexible constructor bodies were added to Java 25 with JEP 513. In this episode of the Inside Java Podcast 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…
