com.objectdb.o.UserException: Ambiguous entity name

I get the com.objectdb.o.UserException: Ambiguous entity name

A former embeddable class seems to be similar to a new entity class. However, I removed the embeddable class from all of my classes. Still I get this error and in the explorer I can find an entry for this embeddable class.

How can I remove this embeddable class without deleting my database or deleting the entity it was related to / nested in?

This problem was solved in version 2.8.2. The exception does not come. It also now seems to be possible to remove the embeddable class in the explorer.
