> InvokeScriptedProcessor works well when started for the first time.
> The Processor become invalid after stopped and cannot be started anymore,
> also after change parameters. This message appears : Unable to load script:
> No processor was defined by the script.
> We have to delete and recreate the Processor to start it.
> The Processor is configured like this :
> Script Engine : python
> Script body :
> {code:java}
