I wouldn't call 4.3 'bleeding edge'. it's over a year since it was
released.  Heck, even Debian has it (though I guess it's not in RHEL).

No one has yet adequately explained why we now have a 'read only'
HotSpot repository.  This isn't about the HotSpot team wanting to keep
using an old version of gcc - this patch is a backported from the
HotSpot tree.

Well, yes.  Indeed I'd expect them to be applied to the HotSpot tree
*first* and then backported to the *stable* OpenJDK6 tree as
appropriate.

Speaking of which, can we have an HotSpot tree we can actually *commit
to* sometime soon?
