Description

Hi,

we just noticed that using the default SshClient we get lots of warning messages in our logs about keep alive requests like this:

08:55:32.122 [sshd-SshClient[40b05dd]-nio2-thread-2] WARN o.a.s.s.c.i.DefaultSftpClient$SftpChannelSubsystem - handleUnknownChannelRequest(SftpChannelSubsystem[id=0, recipient=0]-ClientSessionImpl[XXX@XXX/XXX:22][sftp]) Unknown channel request: [e-mail][want-reply=true]

We're using the SshClient.setUpDefaultClient() function then create our session and finally use the createSftpClient(session) function on a SftpClientFactory.
