This has to do with actually setting the ContextClassloader. Cocoon handles this
in the Servlet's service() method by explicitly calling
Thread.currentThread().setContextClassLoader(this.classloader);
with every request (handles new threads that are introduced.

You can also do this:
super(this.getClass().getClassLoader());
That works as well.
