Java 24 Launch
summary
Java 24 ships with concrete changes: AOT class loading and linking (JEP 483) lands to pre-load and pre-link classes, and instance main and simple source files arrive as preview conveniences for teaching and small scripts. Generational ZGC and virtual‑thread synchronization fixes reduce tail pauses; Project Leiden’s AOT prototype achieves large startup/warm‑up gains (dozens of percent in demos). Panama’s foreign‑function/memory API plus jextract runs an ONNX ML demo. A new Stream Gatherers API provides a stable extension point for intermediate operations and the live demos all run successfully.
