I looked at the question of whether any released jboss-as-arquillian 
container can be used with the current server code base. I found API 
incompatibilities, which could be overcome by adding deprecated APIs the 
delegate to the server, but also semantic incompatibilities which cannot 
be overcome. The released arq containers check for a condition that used 
to be an error in 7.1.2 but is now the correct behaviour.

I'll look at this a little more 
(https://issues.jboss.org/browse/AS7-5613) and see if I can improve 
stability for the future.

For the time being I see no alternative but using a SNAPSHOT of the ARQ 
container or releasing your own fork of it.

Sorry, I meant 7.1.2.Final.
