EAP 7 no longer requires Stateful Session EJBs to use the org.jboss.ejb3.annotation.Clustered annotation to enable clustering behaviour. By default, if the server is started using an HA profile, the state of SFSBs will be replicated automatically. Disabling this behaviour 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 through the configuration of the EJB3 subsystem, in the server configuration.

Note that the @Clustered annotation, if used by an application, is simply ignored, the application deployment will not fail.

When: app contains EJBs with annotation org.jboss.ejb3.annotation.Clustered
Perform: alert the user about the new behaviour in EAP 7.
