Stephen Kraffmiller and I gave a talk called "How to Run a Successful Open Source Java EE Project" at JavaOne 2017 in San Francisco. Here are the slides:
In the talk I mentioned a related case study and I'm writing about transparency and I'd love to get feedback on my draft, which you can find linked from https://github.com/open-organization-ambassadors/open-org-workbook/issues/6#issuecomment-331646784
