So configuration error. The empty check is there because otherwise you create an empty iterator for no purpose. Its always been the case that you might not configure any listeners. Look at the old code which is still there. All I've done is moved the registration to one place instead of the listener (the CCM) having to know about all implementations. In particular I want to make jca and jta optional in the web-profile so you can't assume these things will be configured. Or they may get configured "on-demand" later.
