IMPLEMENTATION NOTE: Servlets whose classnames begin with
org.apache.catalina.
(so-called "container" servlets)
are loaded by the same classloader that loaded this class, rather than
the classloader for the current web application.
This gives such classes access to Catalina internals, which are
prevented for classes loaded for web applications.
