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:
