             Summary: Clarify error message that is generated when @OnScheduled method cannot be invoked
                 Key: NIFI-3111
                 URL: https://issues.apache.org/jira/browse/NIFI-3111
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne
            Priority: Minor


Whenever a Processor throws an Exception from a method annotated with @OnScheduled, we get an error message and bulletin such as:

MyProcessor[id=ac88775c-0158-1000-4de6-52946f9264b5] MyProcessor[id=ac88775c-0158-1000-4de6-52946f9264b5] failed to invoke @OnScheduled method due to java.lang.RuntimeException: Failed while executing one of processor's OnScheduled task.; processor will not be scheduled to run for 30 seconds: java.lang.RuntimeException: Failed while executing one of processor's OnScheduled task.

This is repetition (contains Processor's toString() twice) and also contains the RuntimeException's toString() twice without actually indicating what the problem is. More details are logged in nifi-app.log but the bulletin should be more specific.

I have not verified yet, but a similar problem likely exists with @OnStopped, @OnUnscheduled, @OnScheduled, etc.
