JBossRemoting uses jboss.bind.address in URI like the following:
socket://${jboss.bind.address}:4446/?datatype=invocation

However, if the jboss.bind.address is IPv6, it should be inside
of square brackets.

Invalid URI
socket://::1:4446/?datatype=invocation

Valid URI
socket://[::1]:4446/?datatype=invocation

To reproduce this issue:

Run JBoss instance by the following commend on IPv6 enabled system.
$ ./run.sh -c default -b ::1

Workaround:
Edit JBossRemoting URL not to use jboss.bind.address.

Note:
IPv6 address cannot be parsed with JBossRemoting 2.2.1.GA bundled in 4.2.1.GA. IPv6 parsing needs updated version of JBossRemoting.
