- [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ## Ask your question here 在Dubbo 3.x中只支持了部分2.x中的协议；这样的话我们之前使用到其它协议的项目升级3.0就需要先切换协议，后升级框架，最后按照推荐还需要再切换为triple协议，然后变更注册方式为application，这样是不是走了很多弯路？ 如果2.x能直接支持Triple协议的话，就简单很多了。
1. 配置不同策略的Bean（同一个服务） ```java @Configuration public class ReferenceConfiguration { @Bean @DubboReference(interfaceClass = IdGeneratorService.Iface.class, version = "1.0", timeout = 5000, cluster = "hint") public ReferenceBean idGeneratorService1() { return new ReferenceBean(); } @Bean...
问题发现在dubbo2.5.x，初步分析dubbo3应该同样存在。 问题场景： 消费方和提供方默认的通信SPI均切换到netty4，消费方侧reference配置async=true。在如下的代码场景： Pojo a = new Pojo(); a.setName("zhangsan"); aysncService1.serve(a); Future f1 = RpcContext.getContext().getFuture(); a.setName("lisi"); aysncService2.serve(a); Future f2 = RpcContext.getContext().getFuture(); f1.get()+"--"+f2.get(); 其中aysncService1和aysncService2两个服务引用均采用异步的配置，在netty4场景下，aysncService1.serve(a)，传递给提供方的a对象，属性也编程lisi了，在netty3作为通信组件时，不存在该问题。 初步分析：由于netty4和netty3在客户端的线程模型上有较大的改动。netty3会先将数据序列化后交给nioworker，netty4中直接将对象打包到给nioworker的任务队列，在数据发送时才触发序列化。 解决思路：异步场景发送前对报文深拷贝后丢给任务队列，或者 将序列化前移到业务线程。
