      Netty must be released from RHEL 6.8 x86_64 or compatible so that:

        1) we ship x86_64 version of epoll transport officially, and
        2) we ensure the ABI compatibility with older GLIBC versions.

           The shared library built on a distribution with newer GLIBC
           will not run on older distributions.
