my application dependent on redisson(with netty 4.1.13.Final) and 
async-http-client-2.1.0-alpha26(with netty 4.1.17.Final), 
but netty 4.1.13.Final is this runtime version(decide by maven arbitration)

get java.util.concurrent.TimeoutException all the time 
rather than get exception: 
io.netty.handler.codec.EncoderException: java.lang.NoSuchMethodError:
io.netty.buffer.ByteBufUtil.writeShortBE(Lio/netty/buffer/ByteBuf;I)Lio/netty/buffer/ByteBuf;
(p.s. writeShortBE first introduced in netty 4.1.14.Final)
