I noted this as a todo in the patch: ResponseFilter/RspFilter API: If needMoreResponses() took response and sender as well, class implementations could be Immutable and same instance could be passed to all lookups.

To get the same thing out of one method you'd have to change the return type to something beyond simple boolean, perhaps Boolean but better an enum. This would be a JGroups API change. | I'm not sure you understood what I meant. I agree that we need 2 methods but why not have needMoreResponses() also receive the response and the sender? The problem right now is that I know whether I need more responses based on what isAcceptable() receives!! This makes the filter stateful, I need to cache a boolean and return that in needMoreResponses(). IOW, what I'm asking is that both methods, which have different functions, to receive both the response and sender. That would simplify the ResponseFilter implementation making it Immutable and hence you can always pass the same instance to the remote method call. I know it's an API change but something to keep in mind for JGroups 3.0? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223334#...
