Codereview request for 7171184: Make the failure message in 7168110 more specific

[Rob McKenna]

Hi folks,

David Holmes suggested a rewrite of the original bug (7168110) so I've 
put together the following:

http://cr.openjdk.java.net/~robm/7171184/webrev.01/

It will narrow down the cause of the error and return a more specific 
message when there is a problem attaching jstack to a process created in 
another session.

Let me know what you think,

     -Rob

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:

Webrev at:

Thanks!
