Matt Burgess reassigned NIFI-5230:
----------------------------------
Assignee: Matt Burgess
> InvokeScriptedProcessor can issue a NullPointerException in customValidate
> --------------------------------------------------------------------------
>
> Key: NIFI-5230
> URL: https://issues.apache.org/jira/browse/NIFI-5230
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.6.0
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
>
> 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)
