> When running a org.apache.sshd.server.command.Command, if it happens to close
> the OutputStream instance it is using, then later when the ssh session
> closes, it attempts to flush the output stream before closing it.
> This causes the following warning to be printed on server side
> {code:java}
> WARNING o.a.s.s.channel.ChannelSession#lambda$prepareCommand$0:
> onExit(ChannelSession[id=0,
> recipient=0]-ServerSessionImpl[admin@/0:0:0:0:0:0:0:1:49944]) code=0
> message='' SshChannelClosedException closing shell:
> flush(ChannelOutputStream[ChannelSession[id=0,
> recipient=0]-ServerSessionImpl[admin@/0:0:0:0:0:0:0:1:49944]]
> SSH_MSG_CHANNEL_DATA) length=0 - stream is already closed
> {code}
> and EOF is never sent to client.
