Investigate CDI issue on controller endpoint methods

When trying to use an interceptor on an endpoint method I could not get it to be triggered even though the usual suspects were covered (adding the interceptor to beans.xml etc).

While debugging I noticed that the object create by our ControllerFactory were not proxies as I'd expected to see. Not sure why this is the case but might have something to do with the change a while back when we introduced CDI decorators.
