So I think both names are ok, the current `validateTopics` or any of the names you proposed. As the method does two thing, there will be some side-effect. I am fine either way. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
