Can I have a couple for reviews of a fix for this internal VM test?
When this fix was pushed:
The heap region constructor actually examines the MemRegion that is
passed to it. In the internal VM tests there was a test,
FreeRegionList_test(), that passed a random MemRegion to the heap region
constructor. This worked before, but now stopped working. The original
fix, JDK-8058534, is correct so the fix for the failing test is to set
up proper memory regions and pass those to the heap region constructors.
Before my suggested patch this fails:
$ java -XX:+ExecuteInternalVMTests -XX:+UseG1GC -version
The test fails on this assert in HeapRegion::hr_clear():
assert(_end == orig_end(),
With my suggested patch all tests pass with the above command line.
