        Description

        Most of compiler/rtm/ tests use inflated monitors because by default RTM locking is disabled for stack locks.
        In order to inflate monitor associated with newly created object these tests use method rtm.AbortProvoker::inflateMonitor.
        After that monitor remains released until actual testing begins. If safepoint synchronization happens when monitor unused, then that monitor will be deflated. As a result RTM-based lock elision won't be used and tests will fail.
        Issue could be reproduced w/ +DeoptimizeALot.
