It is a limitation indeed but the only alternative which can be done is to
introduce some ClientResponse class which will have methods accepting the
type of the expected entity and I'm not sure I'd like to introduce just
another Response class...
I think you can register a MessageBodyReader<Response> in addition to other
ones or instead. Inside its readFrom you can create a Response object using
ResponseBuilder, adding the response headers from the map passed to
readFrom() and setting the entity to the result of
WhereProtos.RegistrationCreatedPayload.parseFrom((InputStream). At least
this will hide the parsing code from the user code...
