[logback-user] Tomcat LogBackValve and ${catalina.base}

Hi, I'm running multiple instances of tomcat which share a common ${catalina.home} folder while all specific settings are kept in ${catalina.base} folder. I wanted to use logback-access but noticed LogbackValve uses ${catalina.home} instead of ${catalina.base} when loading loback-access.xml. Shouldn't that be changed to ${catalina.base} knowing that ${catalina.base} defaults to ${catalina.home} when not specified? Regards, Xavier
