Thanks @MazeJack for contributing the code.

A couple of comments:

• I noticed that the code was reformatted. Could you keep the same formatting as the original? The formatting follows the recommended practice for Maven plugins which is different from other Java projects I maintain.
• Could you write a unit test that demonstrates this is fixed?
• I also suspect the issue has to do with the code that calls this method, not code in the method itself. The unit tests, however, will tell us if this code works or not.
