Joe Witt resolved NIFI-7781.
----------------------------
Resolution: Not A Problem
> Nar loading should not impact the loading of NiFi overall
> ---------------------------------------------------------
>
> Key: NIFI-7781
> URL: https://issues.apache.org/jira/browse/NIFI-7781
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.11.4
> Environment: Linux
> Reporter: Joseph Kesselman
> Priority: Major
> Labels: exception-handling
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> No matter what's broken about it, a bad nar should not be able to keep the
> rest of NiFi from running. Catch and handle this exception. And preferably
> give us more information about what the problem was than "unable to load" –
> was file not found, not a valid nar, in conflict with other classes, written
> on a Thursday...
