Hi, The fix is to address https://jbs.oracle.com/bugs/browse/JDK-8016221
Webrev: http://cr.openjdk.java.net/~sjiang/JDK-8016221/webrev.00/Instead to use a fixed port to run a JMX connector, we specify the port as 0:
JMXServiceURL url = new JMXServiceURL("rmi", null, 0);
to allow JMX to select a free port.
and the fix makes sure to close the client and server when the test is
finished (passed or failed).
