( https://hibernate.atlassian.net/browse/HHH-15929?atlOrigin=eyJpIjoiMDI1Zj... ) With 6.2.0.CR3 the original problem still exists. When I remove @Type(JsonType.class) from properties I still get {{Cannot construct instance of org.hibernate.bugs.entities.PropertyTypeA (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value (' {"propertyA":"foo"} ')}} When I add an empty constructor for PropertyTypeA that takes a String it works. So my solution currently looks like this public PropertyTypeA(String json) { // Hibernate needs this constructor, but doesn't use it :-) // See https://hibernate.atlassian.net/browse/HHH-15929 } 🙂 ( https://hibernate.atlassian.net/browse/HHH-15929#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15929#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
