JDK 9, Mission Accomplished: What Next For Java?

on YouTube ↗01h 00m

" summary

JDK 9 ships modularity via Project Jigsaw splitting the old rt.jar into 97 modules (28 are Java SE), encapsulates most internal APIs (notably sun.misc.Unsafe) and adds a big kill switch with modes permit/warn/debug/deny plus --add-exports / --add-opens and jlink to build custom runtimes. Oracle moves OpenJDK to six-month releases, designates LTS every 3 years (JDK 8 LTS, next LTS Sept 2018), open-sources Flight Recorder/Mission Control, and puts local-variable type inference (var in JDK 10) on the roadmap.
