Say for eg: There is a clustered Bean "X" on Jboss server A and B. A and B belong to same cluster. So when Bean "Y" does a lookup on Bean "X" on server A does it always get the local object reference or is there a possibility that it might invoke the method on server "B". I mean does it use client interceptor logic with some optimization in the sense that first check the local binding and then only call remote invoke instead of doing Round robin always.
