StartRequest class in the webapp throw null pointer exception on line 172. The issues is the daemon servlet calls the method request.getPropertiesList("configurationFiles", false); if you do not have any configurationFiles configured in your maven plugin the StartRequest throws null pointer exception. Can be easily fixed by check for null with if (value != null && value.length() > 0) on line 172.
