Bug 1282532

Description of problem:

See https://issues.jboss.org/browse/JBEAP-1882

Version-Release number of selected component (if applicable):

6.4.5.CP.CR2

How reproducible:

Always, but it's a bit of a hack.

Steps to Reproduce:

1. install EAP 6.4.5.CP.CR2 (unzip 6.4.0 and apply a patch)
2. replace the jboss-as-clustering-jgroups JAR in the org.jboss.as.clustering.jgroups module with a newly compiled one that contains this change: https://github.com/wildfly/wildfly/commit/36f5bd99c8 (basically, so that the datagram socket is registered as _unnamed_ instead of named) -- this is to test the unnamed registry, which is otherwise practically unused
3. copy a distributable app into standalone/deployments/
4. start and stop the server

(See also comments in JBEAP-1882 for more context.)

Actual results:

This is a different exception from the one in JBEAP-1882, but it comes from the same code.

Expected results:

No such exception, the unnamed registry should handle unbound sockets gracefully.

Additional info:

IMHO, this is very unlikely to have an impact in real world.
