> The jarsigner command currently does certificate chain validation, but does not check revocation. Users won’t be able to know if the certificates are revoked. This change is to provide an option in jarsigner to enable the revocation check, and to emit progress messages when jarsigner starts network connections to get OCSP responses and CRL.
