Currently in jboss-4.2 the jboss.bind.address is set to "localhost" by default.
There's also some code to fixup the java.rmi.server.hostname to "localhost" when not configured.
This code should be changed to set the java.rmi.server.hostname to the jboss.bind.address when not configured
and the other known bind addresses
jgroups.bind.address (for clustering)
should also be updated to the jboss.bind.address when not configured.
