I'm upgrading from 4.0.5 to 4.2.1, and I'm seeing a problem with the webserver response when I navigate to the JBoss web page. If I use localhost (e.g. http://localhost:8080/), the welcome page loads fine. If I use the actual IP address or the actual fully qualified machine name, it times out. I don't see this under 4.0.5, so I'm guessing something in the startup script or default configuration has changed. Any insight?
...and sometimes you get to answer your own question...
Obey the sticky.
