[18.0.x] Session passivation event can deadlock if it attempts write operations on a session -------------------------------------------------------------------------------------------- Key: WFLY-12729 URL: https://issues.jboss.org/browse/WFLY-12729 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 18.0.0.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Critical Labels: downstream_dependency Fix For: 18.0.1.Final 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.
