我加了-XX:-OmitStackTraceInFastThrow，报错日志也还是上面一样的，没有更多有效日志打印 provider和consumer配置的xml，没有使用dubbo复杂功能，只用了简单的rpc。<dubbo:service 我在测试环境复现出了上面错误，复现场景，一个consumer-A，两个provider-B和C。A调用B和C的dubbo接口，dubbo接口参数是一个枚举类，我在枚举类里新增一种类型NEW，只把A和B升级编译新增了枚举类型NEW，C还是用的老的代码不含新的枚举类型。调用接口的时候A调用B返回200，A调用C返回报错java.lang.IllegalArgumentException: No enum constan。但再多调用几次就会出现上面的报错org.apache.dubbo.remoting.RemotingException: Fail to decode request due to: java.lang.NullPointerException 代码如下： public enum AndroidDevice { } |

org/apache/dubbo/remoting/exchange/support/header/HeaderExchangeHandler.java:97 provider端抓到的，这个provider是更新了枚举类的，理论上应该是返回200 |

另外一个没有更新新枚举类的provider只抓到java.lang.reflect.InvocationTargetException |

jdk8+dubbo3.0.15+spring-core-5.3.27 + k8s部署
近期升级dubbo，配置了xml，没有dubbo复杂功能，只用了简单的rpc。<dubbo:service
interface="com.XXX....IUserService"
ref="userService" />
artahs抓到的报错path=null，报错时attachments=@hashmap[
https://github.com/string[path]:null,
https://github.com/string[remote.application]:https://github.com/string[rest-server],

dubbo只使用了基本功能，消费者和提供者都是简单的xml配置<dubbo:service
interface="com.XXX....IUserService"
ref="userService" />
请各位大佬帮忙看看，这种偶现问题实在难查，而且底层源码报错，dubbo升级不好回滚。详细报错如下：
