Warning:
This jar contains signatures that does not include a timestamp. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2045-07-12) or after any future revocation date.

Applying a timestamp when you sign a JAR is strongly recommended, as it allows you to prove that you signed the JAR during the time interval that your code signing certificate was still valid. This allows your JAR to be validated after the certificate expires thereby prolonging the lifetime of your application.
