Sometimes I'm questioning all my skills... I have a maven based project which uses hibernate as OGM to the mongo database. Everything working fine and already in a productive environment.

Now I changed some lines of code at the business logic to adjust for the changed database model. So far so good.

After compiling and running on the test environment: exception! "no persistence provider for Entity Manager named xy" are you fu***** kidding me? I changed nothing at that point!
