    @yufeldman could you please fix some coding style issues pointed out by @eribeiro (4 spaces
indentation, extra white space, etc)? I'll merge your patch once those comments are addressed.
Thanks.

> As NettyServerCnxn.sendResponse() allows all the exception to bubble up it can stop main
ZK requests processing thread and make Zookeeper server look like it is hanging, while it
just can not process any request anymore.
> Idea is to catch all the exceptions in NettyServerCnxn.sendResponse() , convert them
to IOException and allow it propagating up
