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: EJB 3.0 RC11 - FD
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.
