Hi Team,

We see below warning message when starting the microservice after upgrading
the transport version. According to java doc[1],  SO_KEEPALIVE and
SO_SNDBUF are not channel options for ServerSocketChannels. I created git
issue[2] and did a fix[3] by removing SO_KEEPALIVE, SO_SNDBUF in server
bootstrap class.

2017-12-07 12:32:57 WARN  ServerBootstrap:146 - Unknown channel option
'SO_KEEPALIVE' for channel '[id: 0xac0fb464]'
2017-12-07 12:33:03 WARN  ServerBootstrap:146 - Unknown channel option
'SO_SNDBUF' for channel '[id: 0xac0fb464]'
