Get Ready for the Next LTS Java
summary
JDK 17 is the next JDK 17 LTS target for teams migrating from JDK 8/11; the talk lists concrete language changes from JDK 12–17 (switch expressions, text blocks, records, pattern matching, sealed classes, pattern matching for switch) and API additions that matter in practice: Foreign-Memory Access API, Vector API, UNIX‑domain socket channels and Foreign Linker API. Demos and examples show how var behaves, teeing collectors, improved NPE diagnostics, and which features become final or remain preview—practical migration specifics, not just slogans.
