just FYI - I've made a few consolidation updates in the API during the last week or so, see here for the details:
In summary the updates were around method name and method parameter order consolidation as well as response status getter/setter additions and working with generic types in case of Response and outbound filter contexts (client request, container response) entity setters. I understand that it may be annoying if you have started the implementation already. My apologies for any inconvenience caused.
