JavaOne 2026, 2026 ran 17-19 March at Oracle's Redwood Shores campus, and Oracle timed the Java organisation's annual conference, ran 17-19 March in Redwood Shores 26 release to the opening day, presenting it as the version delivering 10 JDK Enhancement Proposals. Day one: one carried the "Java for an AI World" keynote and the Java 26 release;keynote, day two:two "Java Next" with Brian Goetz and others; others, and day three: thethree a community keynotekeynote, "Java Together... The Power of You" Keynotes, You". The programme added expert sessions, hands-on labs, an unconference and a Hack Haus; highlights were livestreamed to Haus. The headline Oracle announcement was the Java YouTube channel News Verified Portfolio, a curated set of the week included Oracle-supported components led by commercial support for JavaFX and Helidon plus the Java Verified Portfolio, Helidon heading Platform Extension for VS Code. Oracle said support is free for Java SE subscribers and for customers running Java on Oracle Cloud Infrastructure, and framed it as cutting software supply-chain risk. Oracle also said it intends to OpenJDK align Helidon's releases with the JDK and propose it as an OpenJDK project. JVM Weekly added a revived Project Detroit for Java interoperability with JavaScript and Python, embedding the V8 and CPython runtimes through the FFM API instead of reimplementing the languages. The stage was not only Oracle's: JVM Weekly reports Rod Johnson, Josh Long and engineering leads from Microsoft, NVIDIA and Uber in the opening keynote, and JetBrains used the week to announce Koog for Java, its AI agent framework. The release itself was modest by count. The newsletter calls JDK 26 solid rather than revolutionary, with HTTP/3 for the HTTP client and the removal of the Applet API its best-known changes, so the conference announcements drew more attention than the JDK. Oracle's JavaOne page carries the event gallery, with the opening keynote and hands-on labs, and highlights were livestreamed to the Java YouTube channel.
