Brian Stansberry closed EJBTHREE-848.
-------------------------------------

    Fix Version/s:     (was: trunk)

Won't Fix as this is related to StatefulTreeCache which needs to be replaced.

> Currently, each SFSB Container registers an instance of ClusteredStatefulCacheListener with the SFSB cache.  This is inefficient if there are many containers, as each gets passivation/activation callbacks and has to filter for the ones it's interested in. The callbacks don't do anything container-specific, so it should be possible to use a quasi-singleton ClusteredStatefulCacheListener and eliminate the filtering.
> Quasi-singleton, because it's possible to have multiple SFSB caches; need one listener per cache.
