A new ClickStack (i.e. application server stack you can deploy your application on) that supports JBoss 7.2.0.Final has been released (aka JBoss EAP 6.1.0.Alpha), it is called "JBoss72".
In addition to the features supported by the previous JBoss stacks (datasource injection, session store, private mode, stats, etc...), this new version adds 2 new features:
You can now provide a customised standalone.xml configuration file - JBoss' main configuration file. This enables changes to security realms, logging, datasource, etc.
You can also add custom modules to the standard JBoss installation
