Rob Spoor commented on VFS-838:
-------------------------------
A quick attempt to simply replace the dependency gives the following error
during testing:

I have solved similar issues for my own project by changing sshd-core to
sshd-sftp with a newer version, but that comes with its own (quite large) set
of compiler errors.
An alternative could be to change the JSch configuration to add either
{{diffie-hellman-group14-sha1}} or {{diffie-hellman-group1-sha1}} as supported
algorithm.
