[jboss-as7-dev] Confusion with arguments for domain.sh, domain controller vs. process controller

[Brian Stansberry]

Try building this branch:

https://github.com/jbossas/jboss-as/pull/285

It has fixes for your recent issues and changes the help text a bit.

These settings would be rarely used. When you run domain.sh you create a 
process called the ProcessController; that process spawns the 
HostController process and the process for any servers. The PC uses 
sockets to talk to those processes, by default on localhost and 
ephemeral ports. If you don't like that you can use these switches to 
change that.
