[ https://issues.jboss.org/browse/WFLY-10814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Erich Duda updated WFLY-10814:
------------------------------
Description:
*Scenario*
* There are two Wildfly servers configured in cluster
* Both servers have deployment with clustered singleton MDB
* Start both servers
* Check that MDB is active only on one server
* Shutdown server with active MDB
* Check that MDB get activated on the second server.
Sometimes happens that MDB doesn't get activated on the second server. The test waits 60 seconds for it. Always when this issue happens, I can see following exception in the log of the second server which is logged after the first server is shutdown.
The issue was hit with WildFly master built on 9th August (6675410).
*Blocker* priority was set because it is regression against WF 13.
