Hi all,
G1HeapRegionTable#getByAddress() returns incorrect HeapRegion which
contains incorrect address. We can see it in Stack Memory window on
HSDB. Some oop addresses are shown as Free Region (attached image).
G1HeapRegion#getByAddress() should create HeapRegion instance from the
address in _biased_base array.
I uploaded webrev. Could you review it?

I've tested this change with test/hotspot/jtreg/serviceability/sa, it
works fine.
But I received some failure from Mach 5. I also tested this change via
submit repos.

I cannot access this URL. Could you share the result?
How did you submit to mach5 ???
Anyway the failure is with:
