Jira issue originally created by user johnbenz:
Using annotations in my model mapped to "mapped superclass" I can use one to many relations et every bidirectional relation I want.
Using yaml or xml it suddenly doesn't work and throw me an error. Annotations should work the same way and should not authorize one to many or any bidirectional relation.
Comment created by @beberlei:
Its actually the other way around, yml and xml need to allow this, because it works with association overrides.
