We see nightly failures that look like this:
# A fatal error has been detected by the Java Runtime Environment:
# Internal Error (/tmp/jprt/P1/B/143634.ap31282/source/src/share/vm/memory/cardTableModRefBS.cpp:724), pid=3488, tid=10
# guarantee(blk.result()) failed: Non-dirty cards in region that should be dirty
# JRE version: 7.0-b135
# Java VM: Java HotSpot(TM) Server VM (21.0-b05-internal-201103301436.ap31282.hotspot-g1-push-fastdebug mixed mode solaris-x86 )
This failure started appearing after I pushed a changeset that includes the fixes for 7023069, 7023151, and 7018286.
