Can you give some more information about the ClassCastException you see?
> Multiple inharitance levels with generics cause ClassCastException when JPA

> Key: ARIES-1674
> URL: https://issues.apache.org/jira/browse/ARIES-1674
> Project: Aries
> Issue Type: Bug
> Components: JPA
> Affects Versions: jpa-2.5.0
> Environment: Win 7 x64, JDK 1.8.0_73, Karaf 4.0.4
> Reporter: Felix Wassmer
> Assignee: Christian Schneider
> Fix For: jpa-2.6.0
>
>
> 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
