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

    nsk/jvmdi/GetTopThreadGroups/topthrgrp002

The test exercises JVMDI function GetTopThreadGroups(groupCountPtr, groupsPtr).
The test checks if the function returns JVMDI_ERROR_NULL_POINTER:
when groupCountPtr or groupsPtr is null.

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

    sh doit.sh <JAVA_HOME>

Below is example of the test output:

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