I think this changeset: JVM crashes when heavyweight monitors are used
http://hg.openjdk.java.net/jdk7/hotspot-rt/hotspot/rev/c08677f98289
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6840152

is a worthy candidate for inclusion into the jdk6 hotspot.
I would fix the rare but frequently occouring
#  Internal Error (synchronizer.cpp:1954), pid=19400, tid=1185553296
#  guarantee(mid->header()->is_neutral()) failed: invariant
bug.

There exist two oracle bugs that i think are duplicates to this one:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6781744
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7085976
