A StatefulSessionBean with 'passivationCapable=false' is not sticky on a cluster node

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7.1
  • 7.2

Issue

• To disable state replication in a cluster for a StatefulSessionBean the documentation mentions:

  Starting JBoss EAP 7, if JBoss EAP is started using an HA profile, the state of your SFSBs will be replicated. You no longer need to use the @Clustered annotation to enable clustering behavior.

  Disabling this behavior is achievable on a per-EJB basis by annotating your bean using @Stateful(passivationCapable=false), which is new to the EJB 3.2 specification; or globally, via the ejb3 subsystem.

  But this is not the case. When invoking multiple methods on a StatefulSessionBean, different target nodes are being used.

Resolution

There's no Resolution for this issue at the moment.
The workaround for it is to use @Stateless(passivationCapable=true) this will end up in invoking the session bean always on the same node, as long as the node us running; with the downside that the state is replicated.

The issue Jira Content from issues.jboss.org is not included.JBEAP-16057 is scheduled to be fixed in EAP 7.2.2, you might check the release notes of EAP7 maintenance schedule for more details.

Root Cause

Diagnostic Steps

Start a 2 node cluster with an application which contains a StatefulSessionBean and then invoke two methods of this bean. The server.log contains a stack trace like below:

javax.ejb.NoSuchEJBException: WFLYEJB0168: Could not find EJB with id UUIDSessionID [df60651c-42f2-4b7d-b16b-04b2043f0034]
