      Description



      Name: elR10090 Date: 01/29/2002


      The Hotspot VM (build 1.4.0-rc-b91) fails the following test
      from testbase_nsk:

          nsk/jvmdi/events/fieldmod002

      The test exercise JVMDI event JVMDI_EVENT_FIELD_MODIFICATION.
      The test checks the following:
        - if clazz, method, location, field_clazz, field, object and new_value
          fields of the event structure contain the expected values while
          field modifications come from JNI code.

      The test reveals that modification event contains wrong new_value
      if the field is a static object field which is being modified from JNI.

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

          sh doit.sh <JAVA_HOME>

      or for debug VM:

          sh doit.sh <JAVA_HOME> -g

      Running the test outputs:

      java version "1.4.0-rc"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
      Java HotSpot(TM) Client VM (build 1.4.0-rc-b91, mixed mode)
      (watch#8) wrong new value: 0x926380, expected: 0x92632c
      (watch#9) wrong new value: 0x926390, expected: 0x926334
      Exit Code: 97

      Running with debug VM the test outputs:

      java version "1.4.0-rc"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
