[Radim Vansa (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-6829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13460681#comment-13460681 ] 

Radim Vansa commented on ISPN-6829:
-----------------------------------

The problem is in AbstractJCacheNotifier not doing deregistration properly: {{listenerCfgs}} is never pruned, and besides a memory leak this also means that servers send events to nodes that don't have the listener registered anymore.

In case of this test, an event from another test can come just after we've registered the listener (because the node still listens to all events using single adaptor, just does not fire the methods).
