[jboss-jira] [JBoss JIRA] (WFLY-10314) Futures returned by CommandDispatcher.submitOnCluster(...) throw ClassCastException on get() if target node has no corresponding CommandDispatcher

Futures returned by CommandDispatcher.submitOnCluster(...) throw 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 The futures returned by CommandDispatcher.submitOnCluster(...) contain the command execution results per member of the cluster. However, if a given member has no active CommandDispatcher to receive the command, the resulting behavior is not handled, and the Future.get() will throw 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.
