Uninitialized proxy is returned for a query with join fetch

Description

When using Inheritance, there are some situations when an uninitialized proxy instance is returned for a query that has a join fetch.

In my scenario I have the following entities:
1. Event
2. DailyTenantEvent which extends Event
3. User
4. SuperUser which extends User

Now if I run the following queries:
1. Find all DailyTenantEvents for a User.
2. Load that SuperUser mentioned in query1.
3. Find all DailyTenantEvents for a User and join fetch the User entity.

For Query 3, an uninitialized proxy is returned for the User entity even though the fetch it mentioned explicitly.

Attaching maven project. Please look at line 76 in HQLQueryJoinFetchTest.java

Environment

Reproducible Test Case attached.

This bug report does not indicate that the reported issue affects version 5.x. Versions prior to 5.x are no longer maintained.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.

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.
