When the method doesn't have any params there is no need to generate JavaDoc param <Unknown>

We probably need to update the prompt to prevent this. Thanks for reporting will check it out.

@gkorland is there a public repo on which we can test this? We couldn't reproduce this issue at our end. Can you try once more and see if you still get this error.
