Fix request [11u] I backport this for parity with 11.0.22-oracle. No risk, only add a test change. Test passes. SAP nightly testing passed.

As part of this fix, please add -XX:-UsePerfData to some well chosen test that is ran no later than tier 3.

I found no tests in the jdk that disable UsePerfData.

This is really easy to reproduce: java -XX:-UsePerfData -version

Relevant part of stack trace from an hs_err file: V [libjvm.so+0x84c988] HSpaceCounters::update_used(unsigned long)+0x8 V [libjvm.so+0x7e38a5] G1MonitoringSupport::G1MonitoringSupport(G1CollectedHeap*)+0x415 V [libjvm.so+0x7a781e] G1CollectedHeap::initialize()+0x8be V [libjvm.so+0xe42f81] Universe::initialize_heap()+0x41 V [libjvm.so+0xe43242] universe_init()+0x42 Also from the hs_err file, -XX:-UsePerfData. The G1MonitoringSupport constructor makes the _from_space_counters and then calls update_used(0) on that counters object. But because UsePerfData is false, the underlying counter variable object is not created, so _used is NULL and the attempt to set the value of _used crashes. This may have been introduced by 8209062: Clean up G1MonitoringSupport. That change is in the list that's new in the build that was being tested and failed.
