Beam Me Up, Java! Unraveling the Warp-Speed Evolution: A Journey through Java
summary
Market data shows 33% of production environments still run Java 8 and Java 11 covers roughly half, while Java 21 ships in September 2023; vendors like Amazon Corretto, Eclipse Temurin/Adoptium, Red Hat, BellSoft and Azul produce differing JDK binaries and support windows. Concrete, production-ready changes: Java 11 adds a nonblocking HTTP client, single-file run, TLS 1.3 and String/File helpers; Java 17 brings records, pattern matching, sealed classes and ZGC with sub-millisecond pauses; Java 21 adds virtual threads, record/switch patterns and sequenced collections. Support lifetimes and backports vary by vendor.
