That was related to an exception being mapped and Response passed
through the chain again, so no confusions there.
I'm fine with updating CXF for a global post-match filter invoked once,
only when the final resource method is invoked.
Do you think we need to have a minor documentation enhancement request
here (re ContainerRequestFilter) ? Example, explicitly note that global
filters do not apply when a subresource method is invoked but only when
the final resource method is invoked ?
