由于OutOfMemory，无法使用scala-pickling进行序列化？

Question

我正在使用java.nio通道在网络上编写发送对象和数据的代码，并使用scala-pickling进行序列化。 经过多天的调试，我发现我的代码的一些部分在JVM中生成了OutOfMemory错误。那么scala-pickling有什么问题？它无法序列化？

val receivedRequestStr: String = new String(data)
val receivedRequest: Message = receivedRequestStr.unpickle[Message]
val responseRequest: Message = masterController handleRequest receivedRequest
val responseRequestPlk: JSONPickle = responseRequest.pickle
respond(key, responseRequestPlk.value.getBytes)

但我真的不知道为什么，我甚至没有任何暗示。 这是它的错误消息
