Java VM: Trying a new Garbage Collector for JDK 7

Just to clarify, from the comments: this is not the default GC in the latest build of JDK 7 but can be enabled with

  -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC

It's also reportedly slower than the default GC and likely to crash so it's not a good candidate for benchmarks just yet.

Umm... They started talking about this a while ago. It was in the SVN builds. Its nice.

I thought they used mercurial?

Both. Sort of. OpenJDK is on mercurial but core java is still on SVN (I think...). Checkouts here: https://openjdk.dev.java.net/svn/openjdk/jdk/trunk
