      Description

      This may be a known issue but just in case. The heap dumper needs to be updated to work with MVM. If jmap or other tools attempt to obtain a heap dump then the VM core dumps (easy to duplicate - see attached for a sample hs_err file).

      $ java -XRunMServer&
      [1] 23068
      $ MServer > listening on port 1586

      $ java -XUseMServer Test

      $ jmap -dump:file=heap.bin 23068
      Dumping heap to /tmp/foo.bin ...
