JDK-8149460: jmap give unrelated error message if non java process id is specified in the command.

[Gary Adams]

I'd like to close this bug as "cannot reproduce".

The diagnostic output that suggested to use the "-F"
option was removed when the tmtools were decoupled
from the serviceability agent. See JDK-8155091 (May 2016).
