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

             Summary: Futures returned by CommandDispatcher.submitOnCluster(...) throws ClassCastException on get() if target node has no corresponding CommandDispatcher
                 Key: WFLY-10314
                 URL: https://issues.jboss.org/browse/WFLY-10314
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 12.0.0.Final
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


CommandDispatcher.executeOnNode(...) is used to execute a given command on a given member of the cluster.  However, the target member does not have an active CommandDispatcher to receive the command, the resulting behavior is not handled, and the caller receives a ClassCastException.  This is because the RspFilter contained in the RspOptions as passed to the MessageDispatcher is not invoked for unicast requests.

The API will likely need to be adjusted/documented to define what behavior to expect in this scenario.
