biyuhao opened a new issue #2424: Switch-case fall through in ChannelEventRunnable
URL: https://github.com/apache/incubator-dubbo/issues/2424
 
 
   - [x] I have searched the [issues](https://github.com/apache/incubator-dubbo/issues) of this repository and believe that this is not a duplicate.
   - [x] I have checked the [FAQ](https://github.com/apache/incubator-dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
   
   ### Environment
   
   * Dubbo version: latest master branch
   * Operating System version: macos
   * Java version: 1.8
   
   ### Description
   in ChannelEventRunnable#run there is a switch-case fall through which is introduced in https://github.com/apache/incubator-dubbo/pull/1643/commits/b3e91fae80fa6016f0c48884ca0db0f942f2af77 .
   I believe this is a little mistake, and UT is not necessary.
   
   As shown below, there is no `break` statement after `SENT`, I will send a pr later.
   ```
   ...
               case DISCONNECTED:
                   try {
                       handler.disconnected(channel);
                   } catch (Exception e) {
                       logger.warn("ChannelEventRunnable handle " + state + " operation error, channel is " + channel, e);
                   }
                   break;
               case SENT:
                   try {
                       handler.sent(channel, message);
                   } catch (Exception e) {
                       logger.warn("ChannelEventRunnable handle " + state + " operation error, channel is " + channel
                               + ", message is " + message, e);
                   }
                  // no break statement here!
               case CAUGHT:
                   try {
                       handler.caught(channel, exception);
                   } catch (Exception e) {
                       logger.warn("ChannelEventRunnable handle " + state + " operation error, channel is " + channel
                               + ", message is: " + message + ", exception is " + exception, e);
                   }
                   break;
               default:
                   logger.warn("unknown state: " + state + ", message is " + message);
               }
   ```
