[jboss-jira] [JBoss JIRA] Updated: (EJBTHREE-848) ClusteredStatefulCacheListener should be a singleton

ClusteredStatefulCacheListener should be a singleton ---------------------------------------------------- Key: EJBTHREE-848 URL: http://jira.jboss.com/jira/browse/EJBTHREE-848 Project: EJB 3.0 Issue Type: Task Components: Clustering Reporter: Brian Stansberry Assigned To: Brian Stansberry Priority: Minor Fix For: HEAD 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.
