    JAMES-2625 Remove stacktrace upon ClosedChannelException
    
    This stacktrace is especially annoying when behind a load balancer
    doing port checks: connecting and disconnecting straight away, then the
    banner can not be sent to the client.
    
    These checks were encountered with for instance F5 Big Ip load
    balancers.
