      Description



      Name: dkC59003 Date: 09/14/99



      HotSpot Server 2.0beta-C fails the test nsk/regression/b4208030.
      Running the test in debug compiled mode gives assertion failure.
      Mixed mode is OK.
      Both 2.0beta-B and 1.3.0-E pass the test.
      Log and test source follow:

      $ java_g -version
      java version "1.2.2"
      Java(TM) HotSpot Server VM (2.0beta, mixed mode, debug build C)
      $ java_g -Xcomp b4208030
      #
