## How to submit a pull request
Pull requests should be targeted at the branch for the latest stable releases. If the pull request is for fixing a bug which also affects an old branch like `3.x`, we recommend you to submit another pull request for that branch, too.
1. [Rebase](http://git-scm.com/book/en/Git-Branching-Rebasing) your changes against the upstream branch. Resolve any conflicts that arise.
1. Write JUnit test cases if possible. If not sure about how to write one, ask to write one before it's merged.
1. Run `mvn test` before the initial submission or the subsequent pushes, and ensure the build succeeds.
