generics in JPA namedQueries problem in spring data jpa

I have a pretty tricky problem and I think it is related to Spring Data Jpa, I am using 1.0.0.M2.
the named queries work fine if I used generics like this: List<A> methodABCD();
but if I want to use List<A<B>> it stops to work. The error I got is the following.
(does anybody use Generics like this?) .. Thanks in advance.

Caused by: java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.Parameteriz edTypeImpl cannot be cast to java.lang.Class

Ok, this is actually fixed in the spring data jpa snapshot. -cy
