      Description



      Name: icC57033 Date: 11/12/99


      Java HotSpot VM 1.3-O sends wrong buffer contents for event
      JVMPI_EVENT_HEAP_DUMP
      with dump level JVMPI_DUMP_LEVEL_2

      This problem prevents the hotspot_client1.3-o VM from passing the test in debug
      mode:
           nsk/jvmpi/RequestEvent/reqevent005
      which could be found in the HotSpot's testbase:
          /net/sqesvr/vsn/testbase/testbase_nsk

      To reproduce the bug run doit.bat in
      GammaBase/Bugs/<this bug number>
