             Summary: Session remove event can deadlock if it attempts write operations on a session
                 Key: WFLY-12929
                 URL: https://issues.redhat.com/browse/WFLY-12929
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 18.0.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro
             Fix For: 19.0.0.Beta1


Activation/passivation listeners are intentionally non-transactional - and thus should never attempt to perform cache writes.
In order to trigger the requisite activation/passivation listeners, activation/passivation events need to lookup the cache entries relevant to a given session via SessionFactory.findValue(..).  However, if there are entries missing (e.g. a creation meta data entry w/out a access meta data entry), this method will attempt to purge the orphaned entries.  This should never be done within the context of an activation/passivation event.
