suggested fix:
check if tld is null
        ... TldLocationsCache: 447
        TreeNode tld = new ParserUtils().parseXMLDocument(resourcePath, in);
        if( tld != null ){
            TreeNode uri = tld.findChild("uri");
            if (uri != null) {
                String body = uri.getBody();
                if (body != null)
                    return body;
            }
        }

        return null;
