[X] General - JIRA issue associated - Single PR per change - Meaningful commit message [X] CodeStyle - No unnecessary style changes - Check Style passes [X] Documentation - New documentation added - Old documentation updated - Javadocs for public methods [X] Tests - Tests added or adapted - Executed mvn verify or built on Travis Martin, do you want to move this discussion to a new thread and propose a template?
