> Processor: *InvokeScriptedProcessor*
> Script Engine : groovy
> The _InvokeScriptedProcessor_ processor was used to create a custom processor
> in groovy.
> The groovy custom processor exposes the *onStopped* method
>
> {code:java}
> public void onStopped(ProcessContext context) throws Exception {
> System.out.println("Stop")
> restServer?.shutDown()
> }{code}
>
> When the _InvokeScriptedProcessor_ is stopped the groovy processor's
> *onStopped* method is not invoked.
> I ran the InvokeScriptedProcessor processor in remote debug and the cause
> seems to be due to a bug in the management of the scriptNeedsReload variable.
> The groovy processor's onStopped method executes only if the
> scriptNeedsReload instance variable equals false
> !image-2024-01-19-12-41-15-173.png!
> According to my analysis _scriptNeedsReload_ is always set to true due to an
> error in the *reloadScript* method.
> Currently the *reloadScript* method returns true if the script body is empty
> or if there are validation errors, it returns false if there are no
> validation errors.
> The *reloadScript* method should return true if there are no validation
> errors and return false if the script body is empty or if there are
> validation errors.
