Nicolas Noffke ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5a9bd36... ) *commented* on HHH-16247 ( https://hibernate.atlassian.net/browse/HHH-16247?atlOrigin=eyJpIjoiYzJkOW... ) Re: Criteria Query with Object-Typed Embedded Parameter throws AssertionError ( https://hibernate.atlassian.net/browse/HHH-16247?atlOrigin=eyJpIjoiYzJkOW... ) Thinking about this some more, I think this happens primarily because the spring data jpa query method is defined on a generic interface and the type information is then lost at runtime, hence the Object typed param.
