RFR 7116200: (cs) test/java/nio/charset/coders/StreamTimeout.java fails with "Address already in use"

[Jim Gish]

Hi,

Please review the following
Description:

The current code uses the fixed port of 22222 and the test fails if that 
port is in use.  The patch creates the socket on any open port using new 
ServerSocket(0) and then determines the port in use with getLocalPort() 
on the socket.  That port is then used when creating the client.  This 
ensures the test won't fail with "address already in use".

Also, all sockets are closed when done. (Would appreciate comments on 
whether I have engaged in overkill here, or not.)

Patch:

Tests run: jdk_nio3 -- all pass.

Thanks,
   Jim Gish
