jmap - error message when attaching to target process failed is not instructive enough

      Description

      When jmap fails to attach to a target process, it prints:
      "Unable to open socket file: target process not responding or HotSpot VM not loaded. The -F option can be used when the target process is not responding"

      However, there are other options that the user should consider first:
      - Run jmap under the same user account which runs the target process.
      - Run jmap against a core dump file to produce a heap dump.

      Having these suggestions right in front of you in the error message would save less experienced users time finding out what to to.
