Tomcat application context in Debian package contains invalid attribute

I installed tomcat7 and xwiki on a Ubuntu 12.04 following the
instructions from here: [1]. All is working great, but I noticed in
the catalina.out log a small warning:

WARNING: [SetContextPropertiesRule]{Context} Setting property 'debug'
to '0' did not find a matching property.

  1. http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationViaAPT

I looked in /etc/tomcat7/Catalina/localhost/xwiki.xml and the
"<Context" definition contains the debug="0" atribute, which,
according to the tomcat7's (and tomcat6's for that matter)
documentation does not exist for this tag [2], [3].

  2. http://tomcat.apache.org/tomcat-7.0-doc/config/context.html
  3. http://tomcat.apache.org/tomcat-6.0-doc/config/context.html

After I removed debug="0" from the context definition, I didn't got
that warning anymore.

I think you should take this into consideration for the future update
of the packages.
