Yeah, if you get this exception and not doing anything not-"normal" then the chance is high that there are multiple versions of the same class. A possible way to trigger this is when extracting code to a separate module without changing the package. If you copy instead of move and change something you will have a bad time. It is also possible that the IDE complains but building and executing works.

Fun times!
