[COCOON-1270] Javaflow can't call inherited methods

Description

A class named FlowHandler contains this method:

    public void doInvokeMain()
    {
        try {
            setParent(null);
            doInvoke();
        } catch (CommandException e) {
            // Because we are the top level handler, something bad
            // must have happened
            throw new RuntimeException("Unhandled command: " +
                                       e.getCommand());
        }
    }

MenuBarHandler is a class inherited from FlowHandler. The following does *not*
work (from sitemap.xmap):

  <map:flow language="java">
    <map:script src="org.rath.votra.MenuBarHandler"/>
  </map:flow>
[...]
      <map:match pattern="start">
        <map:call function="invokeMain" />
      </map:match>

When accessing the start URI, cocoon produces an InstantiationException.
When I add the doInvokeMain method directly to the MenuBarHandler class,
everything works fine:

    /* If we do not define this method here, we get an
java.lang.InstantiationException
       from cocoon. Seems to be a bug. */
    public void doInvokeMain() {
        super.doInvokeMain();
    }

It seems that cocoon can't call inherited methods as flow handlers.
