             Summary: Multiple inharitance levels with generics cause ClassCastException when JPA is enabled
                 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


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:
