尝试使用 jnetpcap 库读取数据包时发生以下错误。可能是什么原因 ？

ERROR actor.OneForOneStrategy: org.jnetpcap.protocol.network.Ip4java.io.NotSerializableException: org.jnetpcap.protocol.network.Ip4

但它也能够读取一些 Tcp 、 Udp 数据包。

我无法想象为什么会出现这样的错误，但我曾经编写了一段非常有效的代码，用于使用 JnetPCap 嗅探 TCP/UDP 和 RTP 数据包，你可以在我的 GitHub 存储库中以“Lizardous”名称找到它： https:// github.com/Longhitano/main_projects/blob/master/Lizardous/src/j1/lizardous.java
