Please, review this test fix. Issue : https://bugs.openjdk.java.net/browse/JDK-8035395 Webrev: http://cr.openjdk.java.net/~jbachorik/8035395/webrev.00
Currently, the test is using two fixed ports to start JMX connector and RMI registry when necessary. It can not deal with situations when the ports are not available. The patch is adding the ability to obtain ports from the ephemeral range and use them instead of the hardcoded ones. It also tries to minimize the chance of another process stealing the ports by holding the corresponding SocketServers open till right before the port is actually needed.
Thanks, -JB-
