jdk/test/sun/management/jdp/JdpTest.sh got a timeout in jtreg. It appears to be when trying to kill the VM that ran the test.

The log has:

**** Test one ****
Passed

Between writing "Passed" for test 1 and starting test 2 (which immediately would write "**** Test two ****", the script does:

_app_stop(){
   rm ${_lockFileName}

# wait until VM is actually shuts down
  while true
  do
    npid=`_get_pid`
    if [ "${npid}" = "" ]
    then
      break
    fi
    sleep 1
  done
}

My guess is that the VM is overwhelmed by the beauty of this test and refuses to stop, or maybe that there is a zombie process on the machine that is found by _get_pid. I checked on the host that ran the test but found no zombie.
