I had the same problem. I think you can solve as follows.
After register your models, try to change the field's type to link.
OClass oClass =db.get().getMetadata().getSchema().getClass(ClassB.class);
oClass.dropProperty("classToBeReferenced");
oClass.createProperty("classToBeReferenced", OType.LINK);
it worked in my case.
Best Regards,
Robson
