Hotspot crashes while executing as target VM in the following test
from testbase_nsk:

   nsk/jdi/WatchpointEvent/object/object001

The crash is observed for both ladybird and merlin on Solaris 2.7
 
The test exercises com.sun.jdi.event.WatchpointEvent.object() method.
The debugger part of the test (object001.java) creates
ModificationWatchpointRequest for non-static fields of loaded class
in target VM (object001a.java). Then the debugger checks if
WatchpointEvents are received for requested fields.

JDK version
-----------
java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b52)
Java HotSpot(TM) Client VM (build 1.4beta-B52, mixed mode)

Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-beta-b16)
Java HotSpot(TM) Client VM (build 1.3.1beta-b16, mixed mode)

The test will appear in the next testbase_nsk release located at:

    /net/sqesvr.eng/export/vsn/VM/testbase/testbase_nsk

To reproduce the failure please run 'doit.sh' script found in the
directory:
