If you don't timestamp a jar file, jarsigner prints out the warning message:

"No -tsa or -tsacert is provided and this jar is not timestamped. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2016-03-02) or after any future revocation date."

Please remove the words "or after any future revocation date." This is subject to a client's revocation policy, and may or may not be true.
