Failure with entity relationship using discriminator formula

Description

Hibernate has introduced a new code snippet in AnnotationBinder.processElementAnnotations, that validates if the properties are inherited from a super class. If they are inherited, then remaining part of the method is not executed. In our case, it ignores a property as it is coming from a mapped super class. But, it remains ignored and never gets to the place where it is needed. In simple terms, this property comes neither from mapped super class nor from the sub class (ignored by both, assuming the other one processes it). Attached file shows how the entity is related. The error happens when the Notary entity is one-to-one mapped with Person entity on person_id column. Person_id column is not getting recognized from the Person entity hierarchy and exception is thrown (Not a single mapped property exception message)

, I see that targetEntity = ActualPerson.class also works.

An @AttributeOverride should have been added to {ActualPerson to override the column mapping for #personId instead of adding the property, but I see that results in the same failure. I'm guessing that ActualPerson#personId was added to workaround the same failure in an earlier version.

I think this should work with out an explicit targetEntity attribute.

One way I found to get this to work was to explicitly specify the targetEntity on the @OneToOne as follows:

, while the above works and the supplied test case works without failure, should the mapping work without the explicit targetEntity attribute?

Can someone please look into this one?

Can someone help to change the status from "Awaiting Test Case" to "In Progress". I have added the test case to the issue 2 weeks back. But the status has not changed and I don't seem to have access to do so

Thanks Gail for looking into it. But this issue is different from HHH-9485. Here, it happens due to an additional validation added inside AnnotationBinder.processElementAnnotations in newer versions of hibernate. And the error message is Not a single mapped property. I have added a test case to replicate the issue
