Yes - that is how stop-server commands work. Before the --force option
was 100% ignored. Now it is used. If you set --force to false, then
the server will not stop. That's because System.exit() is not called
and your server has non-daemon threads left running - so it will never stop.
See [1] for details

=============================
What this means: The default for --force is true for both types of
servers. Just stick with the default.
