 The Hotspot VM fails to pass the following test from testbase_nsk:

   nsk/jdi/VMDisconnectEvent/_itself_/disconnect002

The test exercises com.sun.jdi.event.VMDisconnectEvent interface.
According to spec of com.sun.jdi.event.VMDisconnectEvent interface, the test
checks that VMDisconnectEvent is received by debugger after invocation
com.sun.jdi.VirtualMachine.dispose() method for debugged VM.

The test works as follows:

the debugger part of the test (disconnect002.java) lanches and connects
to the debugged part (disconnect002a.java) using the default launching connector.
The debugger starts listener thread for listening event delivered from debugged
VM. Then VirtualMachine.dispose() method is invoked. After this the main thread of
debugger waits of terminating of the listener thread using Thread.join() method.
Listener terminates upon receiving VMDisconnectEvent.

The test passes if VMDisconnectEvent is received. If not, the test
fails with interruption caused by timer thread started in debugger.

The failure of this test is observed on ladybird-rc1-b17 and
on merlin-beta-b52 on various H/S configurations:

             Ladybird Merlin

 Windows fails fails
 Sol sparc intmly fails intmly fails
 Sol x86 intmly fails fails
 Linux fails fails
 
were H/S configurations are:

 Windows - P-II 350MHz, 128Mb RAM, Win NT 4.0 SP6
 Linux - dual P-III 600MHz, 512Mb RAM, Linux Red Hat 6.2
 Sol x86 - dual P-III 600MHz, 512Mb RAM, Solaris 8 for x86
 Sol sparc - ULTRA 60 UltraSparc 450 MHz, 512 RAM, Solaris sparc 8

Error message from test output:
----------------------------------------------------
Event received: VMStartEvent in thread main
Invoking VirtualMachine.dispose() for debugee.
Waiting for event listener terminating
Waiting for debugee terminating
Timeout for test execution was exceeded
# ERROR: FAILURE 2: VMDisconnectEvent is not received.
# ERROR: Debugee VM was not terminated yet. Trying to kill it.

nsk.jdi.share.Failure: com.sun.jdi.VMDisconnectedException
       at nsk.jdi.share.EventListener.run(EventListener.java:182)
---------------------------------------------------

The test will appear in the next testbase_nsk release r02 located at:

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

Steps to reproduce:
  1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/<this bug number>
  2. sh ./doit.sh $JAVA_HOME

Input parameter -waittime of nsk.jdi.VMDisconnectEvent._itself_.disconnect002
specifies timeout in minutes for test execution.
