For now we'd ship two standard impls, one of which provides the existing behavior, one of which suppresses HttpSessionListener and HttpSessionAttributeListener notifications when a session is expired due to undeploy. Would it still be possible to have a system property change the default class, or were you thinking jboss-web.xml only? It seems like you might want to change the default globally rather than have to rebuild an application that ran into this problem.
