The workaround with turning off the security manager via command line
options or by granting all privileges to all code bases (mentioned by
Heikki) seems to work.
Still, since the /manager dies with a specific security exception I
tried adding a policy file for the manager only. Unfortunately the app
goes down with the same exception. My manager policy file looks like
that:
//location of the webapp
grant codeBase "file:/usr/share/tomcat6-admin/manager/-" {
permission java.security.AllPermission;
};
and to be sure (since the org.apache.catalina.ManagerServlet is
located in the catalina.jar and is not a part of the webapp):
//location of the library
grant codeBase "file:/usr/share/tomcat6/lib/catalina.jar" {
permission java.security.AllPermission;
};
The latter should not be even necessary since 03catalina.policy
already contains:
grant codeBase "file:${catalina.home}/lib/-" {
permission java.security.AllPermission;
};
which should enable all privileges for the manager app (it's part of
the core catalina codebase).
Unless I'm missing something it looks like the "codeBase" parameter
does not get evaluated properly (that would somehow explain why our
own webapps suddenly stopped working even though the had full
privileges enabled (AllPermissions)).
I have enabled java security debugging (add -Djava.security.debug=all
to JAVA_OPTS in /etc/defaults/tomcat6) to see if I can get more
information. After that gazillions of entries gets logged to
/var/log/daemon.log, there are many failures (during startup) like:

es>)#012#011Active CodeSource: (file:/usr/share/maven-repo/javax/servlet/servlet
-api/2.5/servlet-api-2.5.jar <no signer certificates>)

What's interesting is that is seems to be using the servlet-api from
maven-repo and not the one from /usr/share/java/servlet-api-2.5.jar.
After the request to the /manager I get (only very tiny part shown):
