Is the garbage-first (G1) collector "production ready" in Java 6?

Question

Is the G1 garbage collector still considered experimental in recent versions of Java (6)? Is it safe and ready for production use?

EDIT: I am referring to Oracle JVM.

Answer 1

No as suggest this Oracle article, it's still experimental. It will replace CMS but it seems that it's not quite performant yet : Relative Performance of Java's Garbage First (G1) Garbage Collector?

EDIT :

So now the G1 is "fully supported" in JDK7u4, it not consider anymore as experimental, so I guess it's production ready! .
