As per subject :)

This is the trace:

This is how to reproduce, I instantiate an anonymous implementation of the
interface java.util.concurrent.Callable, the Class.getSimpleName() returns
an empty string... and makes mockito to break :

   public void testRetrySuccess() throws Exception  {
        final Object expected = new Object(); 
        Callable<Object> successLogic = new Callable<Object>() {
            public Object call() throws Exception {
                return expected;
            }
        };

        Callable<Object> spy = spy(successLogic);
        ...
   }

Thanks guys! Fantastic framework.
