[jboss-as7-dev] After throwing a NPE in a DUP, I couldn't Ctrl-C to stop a standalone instance of as7

[Brian Stansberry]

As was mentioned on IRC, turns out it wasn't an MSC bug; the handler for 
composite (i.e. multi-step) operations was blocking in an MSC callback 
method[1], which is a no-no. So I'm fixing that.
