JDK 7 master forest broken; rollback imminent

[Mark Reinhold]

Yesterday's Deployment integration broke the build.  

In order to keep the promotion train moving along, and to ensure that
other groups won't be adversely impacted, I'm going to rollback the
JDK 7 master forest so as to undo that integration.

Yesterday's HotSpot integration will remain intact, and we'll promote
b61 tomorrow as scheduled.

If you've pulled from any master repository other than hotspot since
about 4:30pm PDT yesterday then you'll need to remove those changesets
from your local repositories.  You can do this by saving any pending
changes in a patch, creating a fresh clone, and then applying the patch,
or alternatively by using the hg strip command, which is part of the mq
extension.
