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…

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.

G1 is Java's default garbage collector in most environments and its throughput has been considerably improved in JDK 26 by streamlining its write barriers, which are discussed in this episode together with regions, concurrent marking, and card tables.

In this session, we'll show how the Java Platform is preparing for this paradigm shift in security by adding support for Post-Quantum Cryptography (PQC), which are algorithms designed to be secure against quantum computer attacks. Come to this session to learn about the PQC-related features we've already delivered and what we're working on for JDK 27 and beyond.

Building a compelling desktop app today requires features such as UI controls, charts, interactive media, web content, animation, CSS styling, 2D and 3D rendering, rich text, and property binding, with an easy-to-use programming paradigm that runs cross-platform. JavaFX is all this and more, delivering a rich graphical UI toolkit for building your applications and can also seamlessly interoperate…

JDK 26 was released on March 17, 2026! As with my previous blogs, I have compiled a list of what I think are the most interesting and useful security enhancements in this release. I have also grouped them into appropriate categories (crypto, TLS, etc) which should make it easier to find out what has changed in each specific area.

Let’s quickly review in definitely under 3 minutes the 10 JEPs (JDK Enhancement Proposals) that were included in the JDK 26 release! Couldn't make it to JavaOne? Catch the biggest moments by joining us on our livestreams for the opening Keynote and Community Keynotes right here on the Java YouTube Channel!

Oracle is proud to announce the general availability of JDK 26 for developers, enterprises, and end-users.

Java 26 is getting all packaged up to be shipped worldwide! As with every release of the JDK there are a number of new features, improvements, changes in behavior, and more developers should be aware of before upgrading.

Lazily initializing fields in Java is error-prone and undermines constant-folding. JDK 26 comes with JEP 526, which previews LazyConstant, a type that lazily initializes a value through a given Supplier but still allows constant-folding.

Java 26 is getting all packaged up to be shipped worldwide! As with every release of the JDK there are a number of new features, improvements, changes in behavior, and more that developers should be aware of before upgrading. In this episode of the Inside Java Newscast we will review all the noteworthy changes coming in Java 26 that will impact developers.

The HttpClient will be receiving several updates in Java 26, let's review these changes and what Java users can expect.

Let's review the observability and runtime changes coming in Java 26.

The OpenJDK project is about to release JDK 26 in a few days. This is a good opportunity to add information about notable changes to the stop-the-world collectors in the Hotspot VM.

HTTP/3 is the next version of the internet's most important application layer protocol. In this Inside Java Podcast episode, Nicolai Parlog talks to Daniel Fuchs and Daniel Jelinski about HTTP/3's integration into Java's HTTP client.

This article analyzes why we need to look beyond GC pauses to enable maximal infrastructure efficiency and introduces the new Java API for GC CPU in OpenJDK 26. These capabilities empower engineers and researchers to quantify the collector's CPU overhead, providing the data necessary to make informed decisions regarding the memory-CPU trade-off.

This Heads-Up is part of the regular communication sent to the projects involved; it announces the first Release Candidate builds of JDK 26 and an informal Quality Outreach gathering at JavaOne.

This Heads-Up is part of the regular communication sent to the projects involved; it covers that java.text.DecimalFormat formats floating-point values with the Double.toString(double) algorithm.

Lazily initializing fields in Java is error-prone and undermines constant-folding. JDK 26 comes with JEP 526, which previews LazyConstant, a type that lazily initializes a value through a given Supplier. It executes that supplier at most once successfully and then assigns the value to a field annotated with @Stable, which allows constant folding. This API is also a poster child for how OpenJDK…
