In case of autoload we get a FileNotFoundException with permission denied message, but during startup there is no check for that and we get a NullPointerException in the DocGenerator where NiFi attempts to use it for the first time. It would be better to throw IOException, but those exceptions are caught which is undesirable in this situation. It can be changed later, based on the result of the below mentioned topic. During this task it came up that in which cases NiFi should recover during startup when it is unable to load nars to any reason. After a brief analysis it shouldn't, but it definitely needs more discussion so I've opened a new issue for it: [NIFI-10035](https://issues.apache.org/jira/browse/NIFI-10035) # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [x] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [x] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [x] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [x] Pull Request based on current revision of the `main` branch - [x] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [ ] Build completed using `mvn clean install -P contrib-check` - [x] JDK 8 - [ ] JDK 11 - [ ] JDK 17 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
