-------------------------------------

             Summary: Custom jgroups classes should be registered registered eagerly
                 Key: WFLY-10647
                 URL: https://issues.jboss.org/browse/WFLY-10647
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
            Reporter: Radoslav Husar
            Assignee: Radoslav Husar


If a message is received with configured custom classes (e.g. AUTH) but the receiving stack does not have the protocol, rather than handling and later discarding it, it floods the server log with CNFE.
