> 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!
