code: public static String dot2urlpath(String qualifiedName)
    {
      return qualifiedName != null ? DOT_PATTERN.matcher(qualifiedName).replaceAll(Matcher.quoteReplacement(URL_PATH_SEPARATOR)) : null;
    }
docs: Same as {@link #dot2path(String)} but always uses forward slash as path separator, as used by URLs. Returns null if
  <code>qualifiedName</code> parameter is null.
  
  @param qualifiedName qualified name.
  @return resulting URL path or null.
