[java] update Netty from 4.1.73.Final to 4.1.84.Final

There was one CVE report on Netty since 4.1.73.Final [1] (affecting only
apps running Java version 6 or lower, though), so this patch updates
io.netty up to recently released 4.1.84.Final version [2] to address
that and pick up other bugfixes.

At least, this version update helps to keep security scanners happier.
