>          Issue Type: Bug
>    Affects Versions: 1.6.0

> NIFI-4968 improved the behavior of InvokeScriptedProcessor when the script has an error during parsing/interpretation/compilation, and an improvement was made to not output the same validation errors over and over again until manual action was taken. As part of that improvement though, a bug was introduced where a NullPointerException can occur.
> Proposed fix is not to set the validation results to null on "clear", but rather to an empty Set (which the code is expecting)
