com.alibaba.dubbo.common.Version中有这样的一行代码
```java
// Dubbo RPC protocol version, for compatibility, it must not be between 2.0.10
~ 2.6.2
public static final String DEFAULT_DUBBO_PROTOCOL_VERSION = "2.0.2";
```
它代表的是不是dubbo的发布版本吗？不止是2.6.3有这个问题，以前的版本也是一样的[ Full content available at: https://github.com/apache/incubator-dubbo/issues/2542 ] This message was relayed via gitbox.apache.org for [email protected]
