Codereview request for 7168110: Misleading jstack error message

[Rob McKenna]

Hi folks,

A straightforward enough fix for an issue whereby windows sees fit to 
return a cryptic error message when attempting to run jstack on a 
process created in another terminal session.

As per the webrev, see the remarks section at:
