I'd say I don't agree with you. I think its the other way around. Specify the return statement, it makes it clear what you will receive from the method. No further description indicates that the method doesn't do anything interesting otherwise... Most developers don't use the generated javadoc html page, but the popup in their IDE and there you see the return statement clearly.

But, I will do as you suggest since this is starting to be a long running pull request...
