Thanks, I have to realize I want too much. With the proposed approach I have to maintain a global map to be able to iterate through all active context from different sessions. It can be done, but I don't see how to manage this map on an other node on session failover. My plan was to simply rely on session replication to support clustering my context. Now it seems I can target distribution of my context on top of session replication, or handle session expiration upon undeploy, but not both. At least with a reasonable amount of work. Life is hard :) I am going to target distribution instead, and log a warning on failed destroy.
