      Description

      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.
