The internal build (provided by Karen Kinnear) of
HotSpot 1.3.1beta-b11 (build 1.3.1-internal) fails to pass the tests

nsk/jdi/EventRequestManager/createExceptionRequest/crexreq003,
nsk/jdi/EventRequestManager/createExceptionRequest/crexreq005,
nsk/jdi/EventRequestManager/createExceptionRequest/crexreq007

from testbase_nsk on all platforms (Solaris/Sparc, Linux and win32), except
Solaris/x86.
The tests hang in method Thread.join() when wait for a separate
thread to die. This separate thread asynchronously listens to JDI events
and exits after processing the exceptions InterruptedException or
VMDisconnectedException. These exceptions are thrown by JDI method
EventQueue.remove() if the connection to the target VM is no longer
available (see source file share/EventListener.java from
/net/sqesvr/export/vsn/GammaBase/Bugs/<this bug number>).

For example please look at the test crexreq003 from GammaBase.
This test consists of debugger program (see source file crexreq003.java)
and debugee program (see source file crexreq003t.java).
Debugee throws uncaught exception crexreq003tException which should lead
to the VM exit, but actually the process with the target VM (debugee) does
not really exit after throwing the exception. Therefore the previously
mentioned event listener thread in the debugger VM never ends, and the main
test program hangs.

Note that with previous builds of HotSpot the tests fail with exit code 97
due to a bug 4323439 (nevertheless the process with the target VM really
exits after uncaught exception). Also the test crexreq003 passes
with HotSpot 1.3.1-b11 (build 1.3.1beta-b11) on Solaris/x86,
Linux and win32.

To reproduce the bug run 
doit.ksh <jdk root directory> on Solaris/Sparc, Linux and win32
in
/net/sqesvr/export/vsn/GammaBase/Bugs/<this bug number>
