private void validateStateDescriptorConfigured(SingleOutputStreamOperator<?> result) {
    OneInputTransformation<?, ?> transform = (OneInputTransformation<?, ?>) result.getTransformation();
    WindowOperator<?, ?, ?, ?, ?> op = (WindowOperator<?, ?, ?, ?, ?>) transform.getOperator();
    StateDescriptor<?, ?> descr = op.getStateDescriptor();
    // this would be the first statement to fail if state descriptors were not properly initialized
    TypeSerializer<?> serializer = descr.getSerializer();
    assertTrue(serializer instanceof KryoSerializer);
    Kryo kryo = ((KryoSerializer<?>) serializer).getKryo();
