lotabout ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZTJjZDdkODY5... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16335?atlOrigin=eyJpIjoiZTJjZD... ) HHH-16335 ( https://hibernate.atlassian.net/browse/HHH-16335?atlOrigin=eyJpIjoiZTJjZD... ) Regression: wrong dirty check for converter fields under @Transactional causing entity not saved ( https://hibernate.atlassian.net/browse/HHH-16335?atlOrigin=eyJpIjoiZTJjZD... ) Change By: lotabout ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) h2. What Happened Version: spring boot {{3.0.2}} with Hibernate {{6.1. 7 6.Final}}. With the following simple entity, if we simply put another field to its {{properties}} field, the entity won’t be saved. {code:java}@Table @Entity public class MetaEntry { @Id private String uuid; @Convert(converter = PropertyConverter.class) private Map<String, Object> properties; private String str = "x"; // ... }{code} * The entity won’t be saved after calling {{patchProperties}} function. * If {{@Transactional}} is removed, the entity WILL BE saved. * If {{@Transactonal}} is kept but another field {{setStr}} is modified, then the entity WILL BE saved. {code:java}@Component public class TestService { private final MetaRepository metaRepository; @Autowired public TestService(MetaRepository metaRepository) { this.metaRepository = metaRepository; } @Transactional // will work if commented public void patchProperties(String uuid, String key, Object value) { var meta = metaRepository.findById(uuid).get(); meta.getProperties().put(key, value); // meta.setStr(key); // will work if uncommented metaRepository.save(meta); } }{code} Expected Behavior: The entity will be saved under {{@Transactional}} annotation and if only the {{properties}} gets modified. h2. What Else # I’ve tried the same code with spring boot {{2.7.9}} with Hibernate {{5.6.15.Final}} and all worked fine. # I’ve tried to debug the process and found that the {{loadedState}} of EntityEntry shares the same {{HashMap}} object with user’s {{meta.getProperties}}. h2. Test Case Run {{mvn test}} after extract the attached file. The test {{JpaTest1ApplicationTests#test}} will reproduce the issue. Thanks!
