  @Override public String toString() {
    StringBuffer buffer = new StringBuffer();
    buffer.append("{ ");
    for (Map.Entry<String,byte[]> e : entrySet()) {
      buffer.append(e.getKey());
      buffer.append("=");
      try {
        buffer.append(new String(e.getValue(), "ISO-8859-1"));

        throw new TrevniRuntimeException(error);
      }
