nothing is wrong with it per say - just overhead, as we will call
"newInstance" on the constructor for every code path - test or not.

> 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
