( https://hibernate.atlassian.net/browse/HHH-15929?atlOrigin=eyJpIjoiNWFmYz... ) Hello Thomas Bosch ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5c19f84... ) , thanks for the reproducer using our test templates. JSON support is now standard in hibernate-core, I tried removing the @Type(JsonType.class) annotation and both your examples worked (after providing a default constructor for both property types). San Matus ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) , could you please try updating to Hibernate 6.1.7.Final/6.2.0.CR3 and let us know if the issue persists? In that case, a reproducer which doesn’t involve Spring would be really helpful.
