When I specifically run VersionsJoinTableRangeComponentNamingTest I've got a java.lang.IllegalArgumentException: Cannot determine java-type from given member [null] at org.hibernate.ejb.metamodel.AttributeFactory$BaseAttributeMetadata.<init>(AttributeFactory.java:591) at org.hibernate.ejb.metamodel.AttributeFactory$SingularAttributeMetadataImpl.<init>(AttributeFactory.java:671) at org.hibernate.ejb.metamodel.AttributeFactory$SingularAttributeMetadataImpl.<init>(AttributeFactory.java:661) at org.hibernate.ejb.metamodel.AttributeFactory.determineAttributeMetadata(AttributeFactory.java:542) at org.hibernate.ejb.metamodel.AttributeFactory.buildAttribute(AttributeFactory.java:81) at org.hibernate.ejb.metamodel.MetadataContext.wrapUp(MetadataContext.java:177) at org.hibernate.ejb.metamodel.MetamodelImpl.buildMetamodel(MetamodelImpl.java:66) at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:79) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:752) at org.hibernate.envers.test.AbstractEntityTest.init(AbstractEntityTest.java:94) at org.hibernate.envers.test.AbstractEntityTest.init(AbstractEntityTest.java:82) The member is null because the "property" has a backref getter and hence no member is returned by NORMAL_MEMBER_RESOLVER. I think we should ignore backref properties Does that make sense? If we agree, I will go and apply a fix. http://opensource.atlassian.com/projects/hibernate/browse/HHH-4797 yep, fixed.
