Lyor Goldstein commented on SSHD-983:
-

It does not look like a regular MINA-SSHD code used to create a file system but 
rather more like some reverse engineering that is trying to access only some 
select sections of the code rather than use it in a normal manner - so I don't 
think I can do much. That being said, a quick overview of the code shows the 
problem - the {{DefaultSftpClient}} constructor issues {{SSH_FXP_INIT}} and 
expects to receive a response with a valid version from the server - something 
that does not occur on time. Most likely, the code skipped some vital 
initialization that is usually executed by the regular code.
