JDK 6 Update 21 (JDK or JRE) is Out

I've ran into a few instances where Sun rewrote some fairly major subsystem (like their plugin architecture) on a point release. It's caused quite a few problems.

I'm really waiting for the dynamic language enhancements. They will be great!

hey have been available as experimental options for quite a wile ( http://en.wikipedia.org/wiki/Java_version_history#Java_SE_6_... ), and at least for G1 they seem to still be.

I have the impression, reading the release notes, that compressed oops and escape analysis may be enabled by default now, but I'd be happy if someone could shed some light
