> I have a service interface that returns an object of a class with a (bounded)
> type parameter. One of the properties of this class is an array of of objects
> of this type parameter's type.
> E.g.
> public interface Service {
> Result<A> do();
> }
> public class Result<T extends B> {
> private T[] content;
> public T[] getContent() {
> return content;
> }
> public void setContent(T[] content) {
> this.content = content;
> }
> }
> public class B {}
> public class A extends B {}
> I get the following exception:
> java.lang.ClassCastException:
> sun.reflect.generics.reflectiveObjects.TypeVariableImpl

> I believe the problem is that the JAXBContextInitializer performs a cast
> without checking whether the array's elements are a class or a type variable.
> In case of a type variable the bound of the type variable should (of course)
> be used.
