> See JBS issue for more details. The locks that were native ranking should have a real mutex ranking and participate in the deadlock detection mechanism. The MonitoringSupport_lock is taken out after the Notification_lock, which is aliased to the Service_lock if -XX:-UseNotificationThread. Service_lock is ranked tty-2 which is the same as access rank, so I made a new service rank for these two locks to share. As a future change we should verify that rank+-number doesn't overlap with a different rank.
> Tested with tier1-6 in mach5.
