    Description

      Hi we are faceing issue using port forwarding feature.

      An ssh client is requesting to open a remote connection through Apache sshd server.

      In case connection to remote server fails, there some cases where sshd do not send back SSH_MSG_CHANNEL_OPEN_FAILURE.

      The problem is in org.apache.sshd.common.session.helpers.AbstractConnectionService class 

      The offending code seems to be from line 642 to 654: in case Exception is null, no SSH_MSG_CHANNEL_OPEN_FAILURE is sent back to client.

      We'll try to post a pull request for this issue
