Some minor commenting issues, but otherwise looks good.

test/hotspot/jtreg/vmTestbase/metaspace/stressHierarchy/common/StressHierarchyBaseClass.java line 117:

This comment is unnecessary, as it adds nothing over the log message that follows.

test/hotspot/jtreg/vmTestbase/vm/share/gc/HeapOOMEException.java line 26:

> 24: 
> 25: /**

That doesn't scan so well.  Perhaps something like
"This class is used to distinguish between OOME in metaspace and OOME in heap when triggering class unloading."
