Oracle (RIP Sun) released the Java SE 6 (1.6.0_21) build a few days ago.
Unexpectedly this release has many new features and updates (no security update anyway).
Here are the major ones.
Java VisualVM Updates
Many bug fixes
Many more supported systems
Java Hotspot VM 17.0
The new JVM includes version 17.0 of the Java HotSpot Virtual Machine. This has overall improvements to quality and features such as compressed object pointers, escape analysis-based optimization, code cache management but also G1 garbage collector (not active by default).
Go to grab it while it is hot for testing.
