Back to the Future - Java 8 is here!

" summary

Java 8 adds lambda + streams and a new immutable DateTime API, removes PermGen (old -XX:PermSize flags warn now and are rejected in Java 9), and ships Nashorn JavaScript with tight Java interop. The stream API supports easy parallelism — a Monte Carlo Pi demo runs 32 million samples, ~0.58s sequential and about 2x faster parallel. Implementation fixes land in 8U20/8U40 (forEach optimizations, Nashorn perf). OpenJDK weekly early access builds and a two‑year major release cadence guide adoption.
