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.

Hi Daniel, I believe the three issues can be fixed by https://github.com/openjdk/jdk/pull/5681. Thanks, Lin
