ContainerController might only work for the last item in your list.
You could wrap the DeployableContainer in a more specialized API that you expose in the TestClass via your own Arquillian Extension.
That gives you control to clean up / rest state outside the TestClass it self as well.
I don't think exposing the DeployableContainer directly is a good idea.
Aslak, thanks for the reply. I will create an extension for that and push it back, maybe it could be usefull to other people also.
