我将JsonObject转换为String,然后将它们解析回来.

public static JsonObject clone(JsonObject o) {
  if (o == null)
    return null;

  StringWriter buffer = new StringWriter();
  JsonWriter writer = Json.createWriter(buffer);
  writer.write(o);
  writer.close();

  return Json.createReader(new StringReader(buffer.toString())).readObject();
}

我寻找更优雅的方法.
