--------------------------------------
Hi Pavan,
Currently there are no SASL unit tests - I added GIRAPH-852 for these. I have
not had a chance to test your patch with an existing SASL setup. However the
changes you made related to SASL look fine to me.

> Off late netty 4 has earned so much praise in the community. For example,
> https://blog.twitter.com/2013/netty-4-at-twitter-reduced-gc-overhead
> A switch to netty 4 enables a significant reduction in gc pressure and also
> huge performance gains. I started working on this last Sunday and have a
> patch that shows performance gains on the order of 15-25% (total execution
> time) for some applications at Facebook. However, I only tested it with
> hadoop_facebook. So there might be issues with SASL path.
> I will release the patch today and want to open up a discussion if anyone is
> using the secure feature anymore. If not we can just deprecate it.
