[jboss-dev] Hostname problem when starting JB AS TRUNK

[Jason T. Greene]

OK, I just verified and this is explicitly disallowed in the JDK version 
of JMXSerivceURL (IMO a bug). It is however allowed in URL.

The JBoss implementation of JMXServiceURL does allow it, so the problem 
is that it is not in endorsed libs.
