Bartlomiej Niemiec ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5cdd0b2... ) *commented* on HHH-16997 ( https://hibernate.atlassian.net/browse/HHH-16997?atlOrigin=eyJpIjoiOTIyNz... ) Re: Embedded components in HibernateProxy are not initilized when entity has reference to another entity of the same type ( https://hibernate.atlassian.net/browse/HHH-16997?atlOrigin=eyJpIjoiOTIyNz... ) I don’t think it’s a issue with migration to version 6. As I mentioned this mapping worked in version 6.2.1.Final, in that case version 6.2.2.Final has introduced a breaking change. According to releases notes there were some changes in lazy loading in 6.2.2.Final.
