你好科尔达团队/罗杰，
我已经根据 Yo 模式的示例实现了自定义模式，但是我收到带有消息缓冲区下溢的 Kyro 异常。
我在架构类以及扩展 PersistentStateRef 的实体类中添加了@cordaseriliazation注释
在插件注册表类中，我覆盖了此方法：
@Override
public boolean customizeSerialization(SerializationCustomization kryo) {
kryo.addToWhitelist(PersistentStateRef.class);
return true;
}
下面是堆栈跟踪：

这绝对是 corda 流处理中的一个问题，因为它呈现了 AMQP 错误。
我会再看看当你在最新版本的 corda 中运行使用此架构的流程时会发生什么，看看它们是否会产生类似的问题。
如果您继续面对它，这可能是 Corda 错误而不是您，您可以在此处向 Corda报告问题：https://github.com/corda/corda/issues
