I'm not using monit, so I cannot say about that, but this works for me 
(in Ubuntu 12.04 LTS):
root at opensim:~# cat /etc/init/opensim.conf
start on (local-filesystems and net-device-up and runlevel [2345])
stop on runlevel [!2345]

pre-start exec /usr/bin/screen -p 0 -d -m -S opensim su - opensim -c "cd 
/data/opensim/opensim/bin/ && /data/opensim/opensim/bin/OpenSim.exe"

post-stop script
PID=$(cat /data/opensim/opensim.pid)
screen -r opensim -p 0 -X stuff "shutdown$(printf \\r)"
while kill -0 $PID 2>/dev/null; do
         sleep 1
done
exit 0
end script

You need a PID file of course or the stop will not work at all. Also 
upstart does not monitor if it dies...

The screen options:
-d -m forks screen into the background and forces it to open a new session
-S opensim gives the screen session a name (screen -r opensim will 
connect to it)

The screen command in the post-stop script sends the command "shutdown" 
to opensim and therefore shuts down opensim normally.
The kill & sleep is just there to pause the shutdown of the system until 
opensim has completely shutdown, which can take a couple of seconds. You 
could extend it with a timeout, but I didn't go there.

Daniel
