> Currently for all scripted controller services (ScriptedReader, e.g.) the scripting engine (with additional classpath modules defined by the Module Directory property) is only recreated when the Script Engine property has changed. It should be recreated when the Module Directory property has changed as well.
> In addition, the controller service can be enabled even with an error in the script. The controller service reports internally that it is invalid, but becomes enabled anyway, hiding the invalid status from the user. They may also suffer from the issue in NIFI-4968 with logging while the script is invalid. Instead an exception should be thrown, which prevents the CS from being enabled, then the fix from NIFI-4968 should be applied so that excessive logging does not occur while the CS is invalid.
