Question

Hello Corda团队/ Roger，

我已经基于Yo模式的示例实现了自定义模式，但是我得到消息缓冲区下溢的Kyro异常。

我在Schema类中添加了@cordaseriliazation注释以及扩展PersistentStateRef的实体类

在Plugin Registry类中，我已经覆盖了这个方法：

@Override
public boolean customizeSerialization(SerializationCustomization kryo) {
        kryo.addToWhitelist(PersistentStateRef.class);
      return true;
}

这是stacktrace：

这肯定似乎是Corda流处理中的一个问题，因为它存在AMQP错误。

我将再次查看在最新版本的corda中运行使用此模式的流时发生的情况，并查看它们是否存在类似的问题。

如果您继续面对它，那可能是一个Corda错误，而不是您，您可以在以下位置向Corda报告问题：https://github.com/corda/corda/issues
