Description

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.
