@wangweij Thanks for your review! Regarding your CSR comment if it is necessary to list the `-help` output change, as the current keytool manage lists its commands [1], and then I’ve added an entry for `-version` at the end of the list in the CSR. The jarsigner manpage lists the options [2], and I also added an entry for `-version` to its list. Are you suggesting we should add a new output for `-help` in keytool and jarsigner manpages?
