Backref properties should be ignored when building the JPA 2 metamodel (leading atm to java.lang.IllegalArgumentException: Cannot determine java-type from given member [null]) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-4797 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4797 Project: Hibernate Core Issue Type: Bug Components: entity-manager Affects Versions: 3.5.0-Beta-3 Reporter: Emmanuel Bernard Assignee: Emmanuel Bernard Fix For: 3.5.0-Beta-4 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
