ssh missing cyphers or something

[Benson Margulies <be...@basistech.com>]

When I wrap a service wrapper around an application with an SSH
server, I get these whenever I try to connect. I've compared the java
command-line arguments carefully, and failed to find an explanation.
Can anyone point me at anything to look at?
