In Mustang, by default, jstack and jmap use dynamic attach to talk
to the target process. If the target process is in a state where this doesn't
work , they output a msg such as this:
   
   20510: none of the installed providers knows how to attach to: 20510

On unix machines where the -F option is supported, this msg should be expanded
to also say something like
   Rerun the command with the -F option.
