Hi All Please take a look at
http://cr.openjdk.java.net/~weijun/8130132/webrev.00/ These new warnings will be added to jarsigner: The signer's certificate is self-signed. This jar contains entries whose signer certificate is self-signed. The %1$s algorithm used as %2$s is considered a security risk. For the last one, %1#s is the algorithm name (For example, MD5), %2#s is the option name which is one of "-digestalg", "-sigalg", and "-tsadigestalg". Also, two existing warning messages The signer's certificate chain is not validated. This jar contains entries whose certificate chain is not validated. will be updated to The signer's certificate chain is not validated. Reason: %s This jar contains entries whose certificate chain is not validated. Reason: %s where %s will be the getLocalizedMessage() value of the exception caught in certificate chain validation. Thanks Max
