Hi
Could you review following fix which add sanity check of pid value in
attach mechanism on *nix based platforms.
PID for java process is always positive on affected OS. Hotspot
internally uses signal (SIGQUIT) while attaching. So using negative
numbers as pid might cause very unexpected results and should be prevented.

I checked that jcmd doesn't allow to connect to negative pids.
