[hibernate-issues] [JIRA] (HHH-15716) ClassCastException in QueryParameterBindingsImpl.generateQueryKeyMemento

Emond Papegaaij ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNmM4MDBlYjJj... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15716?atlOrigin=eyJpIjoiNmM4MD... ) HHH-15716 ( https://hibernate.atlassian.net/browse/HHH-15716?atlOrigin=eyJpIjoiNmM4MD... ) ClassCastException in QueryParameterBindingsImpl.generateQueryKeyMemento ( https://hibernate.atlassian.net/browse/HHH-15716?atlOrigin=eyJpIjoiNmM4MD... ) Issue Type: Bug Affects Versions: 6.1.5 Assignee: Unassigned Components: hibernate-core Created: 14/Nov/2022 04:26 AM Priority: Major Reporter: Emond Papegaaij ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) When using an equals restriction on the root of a (sub)query, you get a ClassCastException in QueryParameterBindingsImpl.generateQueryKeyMemento because mappingType is a SingleTableEntityPersister (which is not JavaTypedExpressible ). The example in the testcase does not make much sense, because it was reduced to the bare minimum. In our case a restriction was placed on the root of a subquery, which triggers the same exception. Note that the testcase itself triggers an AssertionError because of the assert just above the cast.
