Java keeps throttling up!
summary
Covers concrete JDK work: CONSTANT_DYNAMIC and improved NPE messages (flag -XX:+ShowCodeDetailsInExceptionMessages), demo of continuations and fibers showing a TCP proxy running on one OS thread with many fibers, Loom early‑access builds and API notes (Continuation, FiberScope, executor changes), Amber features: switch expressions, pattern matching and records (preview) with generated canonical ctor/getters and reflection demo for JSON, Valhalla inline classes with Mandelbrot and int benchmarks showing object‑style code reaching C‑like speed, compatibility caveats (erased generics, equals, volatile) and suggested JDK preview testing.
