> I am currently experiencing an exception that appears to be related to the
> use of the serverSession.shudownOutputStream(); in the
> TcpIpClientChannel.handleEOF method.
> My context is the following
> * Apache Mina sshd client version 2.9.1 on the local side.
> * OpenSSH 5.9 on the remote server side.
> * Local port forwarding port 9000 to remote localhost:8080
> * The error occurs on the Apache Mina sshd client side.
> I intermittently take exceptions on URL connections that are completed and
> they have received the last of the data and is processing the
> SSH_MSG_CHANNEL_EOF
> Any ideas or thoughts would be appreciated.
