Bjørn Hilstad ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiN2JiMWQ2ZTU0... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16719?atlOrigin=eyJpIjoiN2JiMW... ) HHH-16719 ( https://hibernate.atlassian.net/browse/HHH-16719?atlOrigin=eyJpIjoiN2JiMW... ) Upgrading from 6.1.7.Final to 6.2.2.Final breaks Criteria queries for model with inheritance ( https://hibernate.atlassian.net/browse/HHH-16719?atlOrigin=eyJpIjoiN2JiMW... ) Issue Type: Bug Affects Versions: 6.2.2, 6.2.3 Assignee: Unassigned Attachments: hibernate-bug2.zip Components: hibernate-core Created: 30/May/2023 07:37 AM Priority: Major Reporter: Bjørn Hilstad ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) Error message: Cannot invoke "org.hibernate.sql.ast.tree.from.TableGroup.findTableGroupJoin(org.hibernate.sql.ast.tree.from.TableGroup)" because "parentParentTableGroup" is null java.lang.NullPointerException: Cannot invoke "org.hibernate.sql.ast.tree.from.TableGroup.findTableGroupJoin(org.hibernate.sql.ast.tree.from.TableGroup)" because "parentParentTableGroup" is null Discovered while upgrading a spring-boot+jpa app from 3.0.7 to 3.1.0, which upgrades Hibernate from 6.1.7 to 6.2.2. See testcase H8BugTest for a reproducer (the project also contains ways to trigger this from a spring-boot app, but the mentioned one should be good enough). The testcase findStreet which uses a CriteriaQuery to fetch a Street works on all versions. The testcase findAddress which uses a CriteriaQuery to fetch an Address breaks on 6.2.2+, but works on 6.1.7. Address has a simple use of inheritance, which seems to be the trigger of the problem. Versions of Hibernate to use can be controlled from gradle.properties. hibernate-bug2.zip ( https://hibernate.atlassian.net/rest/api/3/attachment/content/50424 ) ( https://hibernate.atlassian.net/browse/HHH-16719#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16719#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
