Here's a further thought - we also need to test the eviction thread with marshalled values. Well, not necessarily the eviction thread per-se, but eviction being invoked via the EvictionManager.processEviction() API - which is used by the eviction thread as well as any external management thread that may wish to schedule eviction.

My reason for concern is that this retrieves keys in order of evictability by querying the data container (which is ordered) directly. Now if these keys are marshalled values, what happens when the EvictionManager calls cache.evict(key)? What should happen is that the MarshalledValueInerceptor detects that the key is a marshalled value already, and does not bother with further wrapping and unwrapping.

However I don't think we currently have a unit test for this.
