Oracle reveals the feature roadmap for JDK 28, a non-LTS release due March 2027, including value objects, generational Shenandoah GC, strictly initialized fields, a standard JSON API, PEM encoding for crypto objects, and ahead-of-time compilation to cut startup time.
Java 25, the latest LTS release, introduces pattern matching for primitive types, module‑wide imports, a compact main method, enhanced records, structured concurrency, scoped and stable values, a vector API, compact object headers, generational Shenandoah GC, AOT optimizations, JFR improvements, security updates, and drops 32‑bit support, offering developers a more concise, safer, and higher‑performance platform.
Java 24 GA introduces 24 JEPs, including Structured Concurrency for safer parallelism, Shenandoah GC as a low‑pause collector, Stream Gatherers for custom stream operations, primitive pattern matching, virtual‑thread improvements, Unsafe warnings, and post‑quantum cryptography, all aimed at modernizing the platform.
