P2 Description
The test sun/tools/jmap/BasicJMapTest.java fails with Mutex rank violations due to the changes for JDK-8273915.
# Internal Error (/scratch/cphillim/hg/18test/src/hotspot/share/runtime/mutex.cpp:291), pid=14632, tid=14677
# assert(_rank <= nosafepoint || _safepoint_check_required == _safepoint_check_always) failed: Locks above nosafepoint rank should safepoint: Dumper Controller lock
#
When the ranks are fixed, the test also gets:
# Internal Error (/scratch/cphillim/hg/18test/src/hotspot/share/runtime/mutex.cpp:390), pid=33218, tid=33341
# assert(false) failed: Attempting to wait on monitor HProfCompressionBackend_lock/20 while holding lock ParallelHProfWriter_lock/21 -- possible deadlock. Should not block(wait) while holding a lock of rank nosafepoint or below.
#
Because of some old check in the mutex rank checking where it assumed special was the least ranked lock.
