[jboss-jira] [JBoss JIRA] (WFLY-10313) CommandDispatcher.executeOnNode(...) throws ClassCastException if target node has no corresponding CommandDispatcher

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-10313?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro updated WFLY-10313:
--------------------------------
    Description: 
CommandDispatcher.executeOnNode(...) and submitOnNode(...) is used to execute a given command on a given member of the cluster.  However, if the target member does not have an active CommandDispatcher to receive the command, the resulting NoSuchService response is not handled, and the caller will receive 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.
