The following test from testbase_nsk crashes the Hotspot VM
(build 1.4.0-rc-b91) on Solsparc platform in all modes:

    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 crash only occurres with boolean, byte, short and char fields.
With int, long, float, double and object fields VM works fine.

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

    sh doit.sh <JAVA_HOME>

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)
