Yes, I would like to see that speedup! Martin claimed on some setup it
reduced the rt.jar building to just 2 seconds (!). Seeing that building
rt.jar currently is one of the most time consuming steps in the build
that would be fantastic.

I think this is fine, it comes with extra tests and is already in jdk7
and jdk6. If the speedup claims are true it would be good to get this
sooner rather than later.

But lets also try to encourage jdk6 to make a new release soon.

Thanks for testing and backporting this,

Mark
