Guessed it was something like that :-)

Any idea when 7 will move into testing mode and 8 will become the main
development arm?  I recall something about February?

Ok, we already have both fixes in IcedTea6.  They are necessary to be able
to build JBoss AIUI.

We've already backported this to IcedTea6 1.9 and it solves the issue with
no further problems so far over the last month.  I'll leave the decision for
OpenJDK6 up to you, but we'll have compressed oops enabled in IcedTea6 unless
something else comes up.

Once we decide which fix to push (7002666 or a disable oops), can we finally get
b21 out the door?
