The JMS example is not used anymore in the Showcase. But there are still dependencies needed to run it on AS 7 and AS 6.
The problem is that particularly, dependency:
is blocking start of Wildfly 8.1.Final when running integration tests.
Because 4.5.x will not run on AS 7 and below anymore, and because JMS example is deprecated in Showcase (we are using instead Push examples) I would remove these dependencies altogether.
