Liferay 7.3.2: when I try to login from the liferay GUI of the general instance, initially I had stackoverflow problem for the resourceBundleLoader (for the override of the @Override method
    public ResourceBundle loadResourceBundle (Locale locale) {
        return _resourceBundleLoader.loadResourceBundle (local);
    }                      ),
but I followed this tip (https://issues.liferay.com/browse/LRDOCS-6316)  to correct the error, but inserting that fix now I am left with the following error:
