GROOVY-8110: @ListenerList generated fireWhatever() method stops working

> @ListenerList generated fireWhatever() method stops working
> -----------------------------------------------------------
>
> Key: GROOVY-8110
> URL: https://issues.apache.org/jira/browse/GROOVY-8110
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime
> Affects Versions: 2.4.7, 2.4.8
> Reporter: Frigo Pratser
> Priority: Minor
>
> As described in the question on SO
> [http://stackoverflow.com/questions/42648766/groovy-listenerlist-generated-firexxx-method-stops-working]
> and confirmed by @aalmiray the fireWhatever() method generated when
> using @ListenerList annotation stops working after some calls.
> [@aalmiray|http://stackoverflow.com/users/120745/aalmiray] s code as posted
> in his reply reproduces the problem with
> Groovy 2.4.7 and I confirmed it with 2.4.8 running it in groovyConsole. The
> difference between this code and the longer one in the SO question is that in
> the longer version the call works but if called periodically after some time
> it produces the same Exception.
