Because the root is secured, there are some pretty weird redirect issues when opening the monitor. It may help to set its security to none in security context.
We tried with <http pattern="/" security="none" />, and that works for an URL ending with '/' (i.e. http://example.org/DataCleaner-monitor/), but without that final slash it still fails.
