> Issue is not valid for 7.2.0.CD12 (upstream client: 12.0.0.Final) therefore we consider this as a blocker.
> Lets have two WildFly servers and same EJB on both. They have nothing to do with each other. And the client app that call beans on them.
> *Scenario*
> # Client invokes _hello_ method on the first server which crash during the call. Exception is consumed. 
> # Client calls successfully _hello_ method on the second one. 
> # Now, the first server is started again and then the client (same thread) try to call _hello_ on the first one. The call should be successful but the client is unable to discover bean.
> {code:java}Exception in thread "main" java.lang.RuntimeException: javax.ejb.NoSuchEJBException: EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/server-1/HelloBean", view is interface ejb.HelloBeanRemote, affinity is None
