[jboss-jira] [JBoss JIRA] (WFLY-5859) NPE in Infinispan when unmarshalling

NPE in Infinispan when unmarshalling ------------------------------------ Key: WFLY-5859 URL: https://issues.jboss.org/browse/WFLY-5859 Project: WildFly Issue Type: Bug Components: Clustering Reporter: Ladislav Thon Assignee: Paul Ferraro Priority: Major In a job {{eap-7x-failover-db-session-shutdown-repl-sync-sybase}} (i.e., a REPL_SYNC failover test where sessions are stored in a Sybase database, but I'm not sure how significant is that), I've seen these NPEs thrown in Infinispan: {code} 12:27:25,723 ERROR [org.infinispan.interceptors.InvocationContextInterceptor]
