Using EclipseLink version 2.4.0.v20111209-r10529

Given this JOINED inheritance example with a primaryKey TenantDiscriminatorColumn I hit the following NPE while EclipseLink is processing the metadata.

@Entity
@Inheritance(strategy=InheritanceType.JOINED)
@Multitenant(value=MultitenantType.SINGLE_TABLE)
@TenantDiscriminatorColumn(name="TENANT_ID", primaryKey=true)
public class Foo {
    @Id
    private int id;
}

@Entity
public class SubFoo extends Foo {

}
