@RogerRiggs  - do you mean to print nothing in the "bad command input" scenario ? The current -XshowSettings launch behaviour prints all data if a bad value is passed to it. I was mimicking this for security subcommands. 

Are you suggesting to print the relevant part of the "java -X" help menu here or is restoring the message with value subcommands sufficient ?
