Hello,
The fix for this bug had to be backed out with '8227178: Backout of
8215523' because it had caused timeout failures for some of the CMS
tests. Those failures get resolved by adding the following check before
calling recalculate_used_stable() in CompactibleFreeListSpace::allocate():
1387 // During GC we do not need to recalculate the stable used value for
1388 // every allocation in old gen. It is done once at the end of GC
instead
1389 // for performance reasons.
1390 if (!CMSHeap::heap()->is_gc_active()) {
1391 recalculate_used_stable();
1392 }
1393
Please review the updated webrev:

This bug is non-public, was it really meant to be?
there does not seem to be anything confidential in the public areas
of the bug. Maybe Poonam can open it after looking at it again, and
eventually open it (and add a token "Description" ;) ).
Thanks,
Thomas
