---------------------------------------------
I think this Jira is more related to Aries JPA. [~ch...@die-schneider.net] what
do you think ?

> --------------------------------------------------------------------------------------

> Key: KARAF-4419
> URL: https://issues.apache.org/jira/browse/KARAF-4419
> Project: Karaf
> Issue Type: Bug
> Affects Versions: 4.0.4
> Environment: Win 7 x64, JDK 1.8.0_73, Karaf 4.0.4
> Reporter: Felix Wassmer
> Fix For: 4.0.9, 4.1.1
>
>
> I'm using inheritance with generics over multiple levels.
> Injecting properties to those beans works fine, but on access of a property
> of the lowest class, there is a ClassCastException thrown.
> I could narrow it down to enabling JPA in the blueprint causing the issue:
> When disabling JPA, the proper bean class is resolved,
> enabled the type resolving stopped at the parent abstract class of the
> expected class, thus throwing a ClassCastException.
> Example project to reproduce this issue:
> https://github.com/fwassmer/inheritance
