----------------------------------
Summary: InvokeScriptedProcessor sometimes does not reload script
Key: NIFI-12309
URL: https://issues.apache.org/jira/browse/NIFI-12309
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.22.0
Reporter: Dirk Arends
In the file InvokeScriptedProcessor.java, the function reloadScript should
return the opposite boolean value similar to the return value of the
reloadScriptBody and reloadScriptFile functions in the same file:
{code:java}
- // return whether there were any issues loading the configured script
- return !results.isEmpty();
+ // return whether there were no issues loading the configured script
+ return results.isEmpty();{code}

Going by the function's return value description, the function should return
true if validationResults is empty:
"@return Whether the script was successfully reloaded"
We've been observing InvokeScriptedProcessors intermittently becoming invalid
after a nifi restart which started after nifi version 1.18 where a related
change *by @mattyb149* was made for NIFI-10387:
