--------------------------------
I gave the built in Nio2 I/O service factory a try and I'm still seeing the
same kind of messages:
{code}
ERROR [nioEventLoopGroup-2-2] io.netty.util.ResourceLeakDetector LEAK:
ByteBuf.release() was not called before it's garbage-collected. See
http://netty.io/wiki/reference-counted-objects.html for more information.
