> If a user supplies an event set that does not exist, then the error message informs the user of this fact.  
> Some end user kind of programmers, but also rookies in Java/Scripting are sometimes lost as to what would be the correct name of an event set name. Also, for Java-unsavvy people the event methods defined in the listener are not as easy researchable for them.
> Now, if we were supplying the available event set names and for each event set the defined events with the error message, then this would help those kind of people tremendeously.
> [PS: Have fixes locally, but would like to apply them in sequence by tackling one open Jira issue after another.]
