yiwuxia opened a new issue #1212: NettyRemotingClient.java's line 144 why mod 999 twice?
URL: https://github.com/apache/rocketmq/issues/1212
 
 
   the code is follow:
    ```
   private static int initValueIndex() {
           Random r = new Random();
   
           return Math.abs(r.nextInt() % 999) % 999;
       }
   ```
   the result  Math.abs(r.nextInt() % 999)  is always equal   Math.abs(r.nextInt() % 999) % 999?
   so why do you write this code ?  necessary?
