Hi Nate,

Attached is an update for https://issues.liferay.com/browse/LPS-48520.

On this pull I also included the two source formatting commits that Jon had on the original pull (https://github.com/natecavanaugh/liferay-portal/pull/2477) for the parent ticket.

Please let me know if there are any issues.

Thanks!
