Please review this test-fix to avoid the problems described in:
Two of the metaspace perf-counter tests fails intermittently when run
with -Xcomp. One reason this has been more frequent lately is a change
to one of the tests that removed a System.gc() call. This call seems to
be more important when running with -Xcomp. Having the System.gc() call
is needed because the PerfCounters are only updated after a GC. And if
any class loading/unloading happens after the call we can't do the
assertions we are doing.
When doing this fix I also realized that one of the tests hadn't changed
UseCompressedKlassPointers to UseCompressedClassPointers, both the
command-line and the test-code used the old version so I updated this as
The updated tests pass in RBT.
