RFR 8006560: java/net/ipv6tests/B6521014.java fails intermittently

[Chris Hegarty]

This test can be seen to fail intermittently on a very busy system. The 
test tries to bind to a "hardcoded" (relative to another) port number. I 
see no reason for specify the port number in this testcase. The socket 
needs to be bound to a specific address, but we should be able to 
specify a port of 0 (ephemeral port).

Exception:
   Caused by: java.net.BindException: Address already in use
