VirtualMachine.dispose() hangs on Windows

Name: elR10090 Date: 06/18/2001



Latest builds of Merlin-beta from (build 1.4.0-beta_refresh-b66)
to
(build 1.4.0-beta_refresh-b68) failed to pass testbase_nsk tests

    nsk/jdi/EventQueue/remove/remove002
    nsk/jdi/EventQueue/remove/remove_l002

on Windows. On the all other platforms tests pass successfully.
Being executed agains earlier builds, right up to Merlin-b65,
tests pass successfully on all platforms including Windows.

These tests launch debuggee VM and invoke
VirtualMachine.dispose()
to check that VMDisconnectedEvent received.
However, on Windows, call to VirtualMachine.dispose() never
returns
and VM hangs.

This test appears in the release r05 of testbase_nsk located
here:

    /net/sqesvr.eng/export/vsn/VM/testbase/testbase_nsk.v14

To reproduce the bug use the simplified version of the test
remove002,
which can be found here:

    /net/sqesvr.eng/export/vsn/GammaBase/Bugs/<this bug number>

Just run 'doit.sh' script using such command line:

    sh doit.sh $JAVA_HOME

Here is log of the test failure on Windows against Merlin-b68:
