> The attached tar file demonstrates the problem. It can be observed as follows:
> {{$ tar -xzf faces-config_xml-exception.tar.gz}}
> {{$ cd faces-config_xml-exception}}
> {{$ mvn jetty:run}}
> Note that the triggering example is absurdly minimalist and contains no Java code since the exception is triggered so early in the webapp execution cycle.
