Nicolas Noffke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5a9bd36... ) *commented* on HHH-16247 ( https://hibernate.atlassian.net/browse/HHH-16247?atlOrigin=eyJpIjoiNjRiMD... ) Re: Criteria Query with Object-Typed Embedded Parameter throws AssertionError ( https://hibernate.atlassian.net/browse/HHH-16247?atlOrigin=eyJpIjoiNjRiMD... ) That is hard for me to answer. You’re right that it would generally be possible (with some effort) to get hold of the concrete types involved. As to the feasibility of doing it in spring data jpa, that is better answered by the maintainers of that project, I’m afraid.
