Indeed. I recently received a pull request to swap Hibernate into a Dropwizard project with a relatively simple data model that was operated on by some simple JDBI repository implementations. The pull requester obviously spent a lot of time on it, and I felt bad rejecting it, but in total the Hibernate impl would have added several thousand lines of code to something that worked perfectly fine as it was. I really don't understand the need to use complex things just because they're popular.
