This directory is only visible to the classloader for Tomcat itself, not
for webapps. There is a special rule that makes servlet classes in
package "org.apache.catalina" available to webapps anyway, however, which
is why the standard WebdavServlet (as well as the other Tomcat features
that are available via servlets) can be loaded.
