Runing "jcmd PID" becomes "help", and giving empty quotes as the command like jcmd PID "" does pass an empty string to parse_and_execute(), but the DCmdIter in there will never find anything to iterate (nor with multiple "" or with " "). bash-4.2$ jcmd 18851 "" 18851: Command executed successfully The CmdLine is the thing that would be returned by DCmdIter, and we don't create empty ones (as things stand today). So this change should be harmless but correct. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20006#issuecomment-2208465886
