Null Pointer Exception when using @NotAudited on an entity with discriminator column, inherited from base entity with InheritanceType.SINGLE_TABLE
--------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-4041
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4041
             Project: Hibernate Core
          Issue Type: Bug
          Components: envers
    Affects Versions: 3.3.1
            Reporter: Priya M


Using latest Envers version -- 1.2.1GA

This is my mapping:

@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
class Foo {

}

@Entity
@DiscriminatorValue("bar")
class Bar {

}


@Entity
@Audited
class FooBarTest {

   @NotAudited
    Bar bar;
}

I get a NPE exception!

Caused by: java.lang.NullPointerException
	at org.hibernate.envers.configuration.metadata.AuditMetadataGenerator.generateInheritanceMappingData(AuditMetadataGenerator.java:305)
	at org.hibernate.envers.configuration.metadata.AuditMetadataGenerator.generateFirstPass(AuditMetadataGenerator.java:349)

	at org.hibernate.event.EventListeners.processListeners(EventListeners.java:181)
	at org.hibernate.event.EventListeners.initializeListeners(EventListeners.java:194)

Right now, I'm forced to make Foo as @Audited even though I don't intend to.
