Jakub ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYWIzMDA5NTNk... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16195?atlOrigin=eyJpIjoiYWIzMD... ) HHH-16195 ( https://hibernate.atlassian.net/browse/HHH-16195?atlOrigin=eyJpIjoiYWIzMD... ) Hibernate 6 fails to bind appropriate type for mapped superclass with generic attribute ( https://hibernate.atlassian.net/browse/HHH-16195?atlOrigin=eyJpIjoiYWIzMD... ) Issue Type: Bug Affects Versions: 6.2.0.CR2, 6.1.7 Assignee: Unassigned Components: hibernate-entitymanager Created: 17/Feb/2023 07:04 AM Environment: java 17 Priority: Major Reporter: Jakub ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) If a base class (mapped superclass) has a generic attribute and there are more than one subclasses (entities) with different (concrete) attribute types, hibernate 6 will incorrectly use the first (alphabetically) attribute type as required for all entities. This in turn causes an exception when trying to query using the generic attribute. Minimal test case: https://github.com/kuba-wu/h6-demo ( https://github.com/kuba-wu/h6-demo ) This used to work in Hibernate < 6. Issue confirmed with latest stable (6.1.7) and devel (6.2.0.CR2).
