The filter used by HA-JNDI could be such a filter. Hmmm, I'm a bit confused here. I clearly understand the performance optimisation here but by doing so, aren't you just going against the abstraction of the JGroups layer? Ok, maybe not entirely against it because clients do need to adhere to passing a ResponseFilter, and whether they pass a RspFilter as well it's up to them but you're effectively promoting implementations to directly tie themselves to RspFilter.
