[jboss-as7-dev] Undeploy due to server shutdown vs. explicit undeploy operation

[Brian Stansberry]

The org.jboss.as.controller.ControlledProcessStateService service is 
meant to be used for this kind of thing. But, the case of stopping via a 
soft kill instead of a management op isn't properly handled. For that, 
someone would need to do

https://issues.jboss.org/browse/AS7-4492

There was a dev list thread in April related to this; it's linked on the 
JIRA.
