JPQL TYPE() operator not working on attributes

Description

This query didn't work:

– A –

it returned an empty result - but the equivalent query below did work:

– B –

It seams that Hibernate handles the TYPE operator on a attribute (that in may case is of the same class as the root query class) in a bizarre way. Below is a translation of the query A to SQL:

the c.dynamicSuperclass attribute is nether joined in this query and TYPE(c.dynamicSuperclass) is actually treated as TYPE(c).

Still problematic in hibernate 5.

As part of verifying that this issue affects 5.0, please just set the "Affects version". Leave the "verify-affects-5.0" label and leave the issue in "Awaiting Response" status; these are critical for us to be able to track these verifications and triage them. Thanks.

This bug report does not indicate that the reported issue affects version 5.x. Versions prior to 5.x are no longer maintained. It would be a great help to the Hibernate team and community for someone to verify that the reported issue still affects version 5.x. If so, please add the 5.x version that you verified with to the list of affected-versions and attach the (preferably SSCCE) test case you used to do the verification to the report; from there the issues will be looked at during our triage meetings.
