[Emmanuel Bernard (JIRA)]

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.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.
