Maxscale init script - --user=maxscale: command not found

When i try to start maxscale 1.2.0 via initscript i get the following error:

service maxscale restart

/etc/init.d/maxscale: line 48: --user=maxscale: command not found

I had to change line 48 of "/etc/init.d/maxscale" (adding quotes) to:
DAEMON_OPTS=" --user=maxscale"
to get it work without error message.

Nevertheless maxscale is not running as user maxscale but as user root.
