Artyom Dmitriev ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=63da4f7... ) *commented* on HHH-16122 ( https://hibernate.atlassian.net/browse/HHH-16122?atlOrigin=eyJpIjoiZTAxMT... ) Re: Named type [class xxx] did not implement BasicType nor UserType ( https://hibernate.atlassian.net/browse/HHH-16122?atlOrigin=eyJpIjoiZTAxMT... ) I can confirm that the error happens when @Type is applied to a field/getter in a @MappedSuperclass. A possible (not a very nice) workaround might be to switch to property-based access, mark the property @Transient and override it in the child class. I am surprised HIbernate does not provide a way to customize AttributeFactory or to use my own JpaMetamodelImplementor implementation. That would help to solve the issue without the need to wait for an official fix.
