what's means of jinfo non-default vm flags? non-default is an ambiguous, I think it looks like default vm flags.
jinfo
jinfo prints those VM flags which value is either overridden by a command-line option or set by the VM ergonomics policy. In other words - the flags with a value different from the built-in default.
