nullability of property is checked even if hibernate.check_nullability is set to false -------------------------------------------------------------------------------------- Key: HHH-5791 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5791 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.0 Environment: Hibernate 3.6.0-Final, MySQL Reporter: Paweł Kępka In our application we use a subclass of org.hibernate.cfg.beanvalidation.BeanValidationEventListener which integrates with Spring for entity validation. In order to wire our class we use following configuration: hibernate.ejb.event.pre-update=com.acme.SpringBeanValidationEventListener hibernate.ejb.event.pre-insert=com.acme.SpringBeanValidationEventListener javax.persistence.validation.mode=none hibernate.check_nullability=false But this stopped to work when we tried to switch from Hibernate 3.5.3 to 3.6.0. When we try to merge an entity which has a null property with @NotNull annotation and nullable set to false we get: java.lang.NullPointerException: null entities are not supported by org.hibernate.event.def.EventCache at org.hibernate.event.def.EventCache.containsKey(EventCache.java:80) at org.hibernate.event.def.DefaultMergeEventListener.mergeTransientEntity(DefaultMergeEventListener.java:361) at org.hibernate.event.def.DefaultMergeEventListener.entityIsTransient(DefaultMergeEventListener.java:303) at org.hibernate.event.def.DefaultMergeEventListener.onMerge(DefaultMergeEventListener.java:258) at org.hibernate.event.def.DefaultMergeEventListener.onMerge(DefaultMergeEventListener.java:84) at org.hibernate.impl.SessionImpl.fireMerge(SessionImpl.java:867) at org.hibernate.impl.SessionImpl.merge(SessionImpl.java:851) at org.hibernate.impl.SessionImpl.merge(SessionImpl.java:855) at org.hibernate.ejb.AbstractEntityManagerImpl.merge(AbstractEntityManagerImpl.java:686) instead of ConstraintViolationException. Setting nullable to true resolves the problem but it is temporary solution only. The whole issues might to be related to HHH-5437.
