provider服务端配置serialization="kryo"自定义异常类抛错时消费端捕获不到

[netsail]

provider 服务端配置 serialization="kryo" 自定义异常类抛错时，消费端 kryo 序列化后捕获不到异常,以下是报错信息：

method:org.apache.dubbo.rpc.protocol.dubbo.DecodeableRpcResult.decode(DecodeableRpcResult.java:148)
 [DUBBO] Decode rpc result failed: com.esotericsoftware.kryo.KryoException: Class cannot be created (missing no-arg constructor): java.lang.StackTraceElementSerialization trace:stackTrace (org.apache.dubbo.rpc.RpcException), dubbo version: 2.7.0, current host: 127.0.0.1
java.io.IOException: com.esotericsoftware.kryo.KryoException: Class cannot be created missing no-arg constructor): java.lang.StackTraceElementSerialization trace:stackTrace (org.apache.dubbo.rpc.RpcException)

我们自己的解决方案是在 dubbo-serialization/dubbo-serialization-kryo/src/main/java/org/apache/dubbo/common/serialize/kryo/utils/AbstractKryoFactory.java 类中添加：

kryo.addDefaultSerializer(Throwable.class, new JavaSerializer());
