Well, I haven't exhausted yet. Are you sure your new abstract class
implementation works? I still think you have type erasure with your
solution. To test my theory I tried this:

public class TestIt
{
    public static abstract class MyInvocationCallback<T> extends
GenericType<T>
    {
       public abstract void complete(T value);
    }

    public static class GenericInvocationCallback<T> extends
MyInvocationCallback<T>
    {
       @Override
       public void complete(T value)
       {
       }
    }

    public static void main(String[] args) throws Exception
    {
       GenericInvocationCallback<List<String>> callback = new
GenericInvocationCallback<List<String>>();

       System.out.println(callback.getRawType().getName());
    }
}


And it failed with an IllegalArgumentException

Exception in thread "main" java.lang.IllegalArgumentException:
org.jboss.resteasy.core.ServerResponse.org.jboss.resteasy.core.ServerResponse$MyInvocationCallback<T>
