Change default subsonic-user on tomcat on FreeBSD

[MacGyves]

Hi,

I would like to know how to get rid of the warning message "Warning! The Subsonic process is running as the root user. Please consider to change this." which appears after the login into subsonic's web interface.

Got the following constellation:

* FreeBSD 9.2-RELEASE-p12
* Tomcat v8.0.12
* Subsonic 5.0 WAR

I succeeded to deploy and start the WAR to Tomcat, and was able to log into subsonic's web-interface.
Tomcat spawns 2 jsrv - processes: one as root, one as www.

Read in other posts that a SUBSONIC_USER has to be set in a config file. So I added SUBSONIC_USER=www to /var/subsonic/subsonic.properties, since that file seemed to be the most appropriate. The warning prevails, though.

Concerning my motivation: I wanted to re-use my instance of Tomcat running in a jail, therefore I decided to go with the WAR-installation, and not with the standalone.
