This seems to be the culprit here: your ConfigurationValue.toString()
passing a null value to String.concat() and a NullPointerException is
being thrown. This seems to be happening when Tapestry's ExceptionReport
page tries to show the session attribute values. So that's why the error
page is being served by Jetty, not by Tapestry: ExceptionReport throws an
unhandled exception during its rendering. ;)
