> when I upgrade zookeeper from 3.4.13 to 3.5.7 in my application, I find the function processCmd in ZooKeeperMain.java is just like blow
> {code:java}
> protected boolean processCmd(MyCommandOptions co) throws CliException, IOException, InterruptedException {
>     boolean watch = false;
>     try {
>         watch = processZKCmd(co);
>         exitCode = ExitCode.EXECUTION_FINISHED.getValue();
>     } catch (CliException ex) {
>         exitCode = ex.getExitCode();
>         System.err.println(ex.getMessage());
>     }
>     return watch;
> }
> {code}
> it throws {color:#FF0000}CliException {color}which has been caught in the funciton, so I think it can be removed.
