Episode 62 “JDK 27 + Valhalla, Now! + Hackathon” [IJN]

Posted on July 19, 2026

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.
