When running under Liferay Portal 6.2, if the WEB-INF/portlet.xml descriptor does not contain a resource-bundle element, then calling PortletConfig.getResourceBundle(Locale) returns an instance of java.util.ResourceBundle that throws a NullPointerException for every method call. This may or may not be a bug in Liferay Portal. But since the problem exists in Liferay Portal 6.2 CE GA6 (the final open source release) it must be worked-around in the bridge.

The workaround is to have liferay-faces-bridge-ext decorate the BridgePortletConfigFactory so that it returns an empty java.util.ResourceBundle when necessary.
