Čedomir Igaly ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16759 ( https://hibernate.atlassian.net/browse/HHH-16759?atlOrigin=eyJpIjoiNzQ2ZT... ) Re: Merge fails when entity has an Embedded Java record ( https://hibernate.atlassian.net/browse/HHH-16759?atlOrigin=eyJpIjoiNzQ2ZT... ) Java records are by definition immutable, but org.hibernate.type.ComponentType#replace is ignoring that and trying to replace single changed property. Adding simple check to return original object when component class is record will fix this particular problem.
