Major Description
If there are beans defined in the blueprint with a "class" attribute referencing an interface instead of a class, the JPA blueprint AnnotationScanner fails with a NullPointerException.
During the annotation scanning, the assumption is made that the class hierarchy will eventually hit the Object.class, while an interface Class<?> will return null when the getSuperclass() is called.
While it may not be a common use case to reference an Interface in a bean definition, I have a rather specific use case where I am using a factory class with a factory method to return an implementation of an interface.
