I am almost certain that what you describe is a regression introduced with HHH-12993 Open . I've just reported a very similar issue in HHH-13670 Open , which is also an regression caused by this issue that shipped in 5.4.5.

Please check if your case works by disabling the omission of supertables in queries:

<property name="hibernate.query.omit_join_of_superclass_tables" value="false"/>
