[systemd-devel] behavior of stop in case of multiple processes

Hello.

I am trying to use systemd to run wildfly application server. It is
being run by a shell script that runs a java vm in a separate process.
So, killing the script does not kill the other process.
The service is a simple type service, and I am wondering what happens
there on stop. when the server receives signal sigint or sigterm
directly it logs some messages about it being stopped. However, when I
start it and then stop, this does not happen, i get no message as if
it was killed by sigkill.
What may happen? the documentation says that the systemd sends sigterm
to all processes by default (if KillMode=control-group and this is
probably default), and then sigkill if processes do not respond for a
configured amount of time.
In this case sigterm sent to the shell script (the main process)
causes it to exit, but then appserver is probably sigkilled.
I know that setting sendSIGKILL to no makes it shudown normally. What
is going on?
