Well, I was thinking more about the need for socket bindings at all. After all, we don't (currently) want to expose this queue from the outside. I am thinking of the `invm-connector` instead of `netty-connector`. Take a look at https://docs.jboss.org/author/display/WFLY8/Messaging+configuration for reference (It's the wildfly version, but it should be fairly similar).
