RFR: JDK-8025211 - Intermittent test failure: java/net/DatagramSocket/PortUnreachable.java

[Mark Sheppard]

Hi
please oblige and review the following changes

http://cr.openjdk.java.net/~msheppar/8025211/webrev/
which address the issue raised in the bug
https://bugs.openjdk.java.net/browse/JDK-8025211

an intermittent failure occurs on some windows test machines.

this replaces a Thread.sleep(5000) with explicit synchronization between 
sender
and receiver via a CountDownLatch

regards
Mark
