Subject [jira] [Commented] (ARIES-1533) JPA blueprint AnnotationScanner is unable to handle Interfaces
Date Fri, 15 Apr 2016 11:02:25 GMT


Christian Schneider commented on ARIES-1533:

A null check probably will not hurt but I would like to first really understand your use case.
Can you give an example how this bean looks like?

>          Issue Type: Bug
>          Components: JPA
>    Affects Versions: jpa-2.3.0
>            Reporter: Jurriaan Heuberger
> 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.
