[jboss-as7-dev] Port conflict 8080 detection?

[Cheng Fang]

I already have other servers running on port 8080, and then forgetfully 
starting AS7 standalone server, and it started successfully without any 
complaints.  The main root page localhost:8080 stills displays the 
content from the other server, but localhost:9990 does display as7 
management console.

Is there a port conflict detection, or is it designed this way?  I think 
it would be helpful to fail fast once a port conflict is detected.
