Hi,
Why table for an abstract class with inheritance strategy TablePerClass is created? Is not it that tables are created only for concrete classes for TAblePerClass inheritance strategy?

Use a mapped superclass instead of marking it as an entity if you do not want a table for that class. I've been told that from a JPA perspective, entities can be used within queries, while mapped supperclasses cannot. So all entities require associated tables or they cannot be put within queries. Even though an abstract entity cannot be instantiated, queries using it could return raw data or to filter other entity results.

Best Regards,
Chris
