The following tests failed:
gc/gctests/Compact/compact017 (gc.gctests.Compact.compact017)
gc/gctests/Compact/compact018 (gc.gctests.Compact.compact018)

The assert triggered below was introduced in the recent fix for 6472335.
It does not indicate a correctness issue (see comments), just a very minor
performance issue.

For example:

#
# An unexpected error has been detected by Java Runtime Environment:
#
# Internal Error (/net/prt-solx86-q1-3/PrtBuildDir/workspace/src/share/vm/memory/concurrentMarkSweepGeneration.cpp, 1169), pid=1196, tid=14
#
# Java VM: Java HotSpot(TM) Client VM (20060922160805.ysr.bot-debug mixed mode)
#
# Error: assert(top < _icms_stop_limit,"Tautology")
