Best practice is to use the JIRA issue title in the pull request title and in the first line of the commit message. - [x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will be performed on your pull request automatically. - [ ] You have run the [Core IT][core-its] successfully.
