   Hi @cgivre,
   
   Actually, the changes that I have made is not with the intent of merging to 
the codebase. It's more of a demonstration of Netty jar up-gradation. As we 
tried to upgrade the Netty jar, we found there are many breaking changes that 
have been introduced. 
   So, the issue is not to resolve the conflict and merge the code. It's about 
how can we upgrade some jars that are being used in opensource code.
   We have tried to upgrade from our end and modify the code accordingly. But, 
it didn't seem to work. If there is some suggestion on how to upgrade some of 
the jars used by open-source code or should we wait for the Netty jar 
up-gradation by the open-source community?
   
   Regards,
   Alka

> Hi,
