      Description



      Name: pvR10198 Date: 05/28/2002


      The following test from testbase_nsk crashes the Hotspot VM
      (build 1.4.1-beta-b13) on all platforms in all modes:

          nsk/jvmdi/IsMethodNative/isnative002

      The test exercises JVMDI function IsMethodNative(clazz, method, isNativePtr).
      The test checks if the function returns:
        - JVMDI_ERROR_INVALID_CLASS if clazz is null
        - JVMDI_ERROR_INVALID_METHODID if method is null
        - JVMDI_ERROR_NULL_POINTER if isNativePtr is null

      To reproduce the bug run script in GammaBase/Bugs/<this bug number> directory:

          sh doit.sh <JAVA_HOME>

      Running the test with verbose option reveals that call
      IsMethodNative(clazz, method, NULL) causes the crash:

      % sh doit.sh <JAVA_HOME> -v
