    Description

      After fixing JDK-8230731, and removing HeapDumpTestWithActiveProcess.java from the problem list, it now fails with:

      sun.jvm.hotspot.types.WrongTypeException: No suitable match for type of address 0x0000000800000068

      This is basically the same issue as JDK-8235220. There's just a different location that needs to deal with the WrongTypeException. It's in ObjectHeap.iterateLiveRegions(). A WrongTypeException handler is needed:

            catch (AddressException e) {
              // This is okay at the top of these regions
                }
            catch (UnknownOopException e) {
              // This is okay at the top of these regions
            }
