All The Way To 11: The Future of Java
summary
Java arrives at JDK 11 with concrete changes: modularity splits the old RT jar (4,500+ public classes) into ~75 modules (27 in Java SE), requires encapsulation of internal APIs and jlink-built runtime images, and removed legacy modules (applets, java.se.ee). Oracle moves to six‑month releases with an LTS every three years; JDK 11 is LTS while Oracle changes licensing so production use of the Oracle JDK needs an Oracle JDK subscription (OpenJDK builds get six months of updates). Language and VM work includes var local inference, single‑file source launch, flight recorder open-sourced, and ongoing projects Valhalla (value types) and Loom (fibers).
