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

             Summary: Possible race between remote process' receipt of a cancellation request and its receipt of the initial request
                 Key: WFLY-3381
                 URL: https://issues.jboss.org/browse/WFLY-3381
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Domain Management
    Affects Versions: 8.1.0.CR2
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
             Fix For: 9.0.0.Alpha1


It's possible that if a managed domain operation that sends a request to another process in the domain is cancelled immediately after initiating sending of that request that the cancellation request will be received *before* the original request. If that occurs, the cancellation request will fail (as there is no ActiveOperation to cancel) and then the original request can hang waiting for a tx commit/rollback that will never arrive.
