So an "eviction" element with no "executor" child element means JBC doesn't run eviction, but lets me do it with my own thread? That's what I'd like. Besides that, +1 on allowing injection of the ExecutorService(s). Wherever possible, services that run in the AS should allow injection of centralized thread pools for this kind of stuff.
