             Summary: Uploaded NAR hits Error and stays Installing
                 Key: NIFI-13757
                 URL: https://issues.apache.org/jira/browse/NIFI-13757
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Bryan Bende
            Assignee: Bryan Bende


The NarInstallTask has a try/catch for Exception, but in some cases attempting to load the actual extension class may produce a sub-class of Error which is not caught but the task, so then the state never gets updated to FAILED and the error message never gets set.

In addition, at the point during which it hits the Error, the NAR has already been registered in ExtensionManager, and future calls to get available extension types will see the bundle and attempt to access the extension definitions, which also encounters the same Error and fails the overall request. This should be made more lenient to still allow all the other available extensions to be returned.
