Jolokia on tomcat with hidden server version

[cgio1]

Hi,
I`m trying to use jolokia on a tomcat 7 server with the war agent.
The server was configured to surpress tomcat version by the serverinfo.properties file in $TOMCAT_HOME/lib/org/apache/catalina/util for security reasons.
Jolokia generally works, but it fails to deliver metrics like session information of the applications on that tomcat.
Is it possible to force jolokia to use tomcat detection, so I can use it to check metrics of the deployed applications?
Thanks and regards,
Chris
