To Java 22 and Beyond!
summary
Java 22 rounds out recent work: virtual threads provide a lightweight thread model (roughly 4KB each) enabling millions of concurrent tasks and straightforward blocking code; pattern matching for switch and records simplify deconstruction and exhaustiveness checks; Project Panama’s foreign function and memory API replaces JNI for safer native calls; Generational ZGC becomes production-ready (Netflix reports it outperforms G1 for many workloads); sequence collections, unnamed patterns, CDS auto‑archives, a simple web server, and multi‑file launch improve ergonomics. Several features remain preview/incubator.
