Tassilo Karge ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5f50ce4... ) *commented* on HHH-16512 ( https://hibernate.atlassian.net/browse/HHH-16512?atlOrigin=eyJpIjoiYzlmYz... ) Re: Bidirectional OneToOne association produces wrong isNull predicate in criteria query ( https://hibernate.atlassian.net/browse/HHH-16512?atlOrigin=eyJpIjoiYzlmYz... ) You are right, the tested change is incorrect, though the test I built shows that the query built by hibernate without the change is also incorrect for both the current version (6.2) as well as the last 5.x version of Hibernate.
