Subject: [jRuby] net/ssh unsupported algorithm: DSS1withDSA (OpenSSL::PKey::PKeyError)

I've migrated from CRuby to jRuby with the same code for ssh connection.
However, within jRuby i get this error message :
Exception in thread "AWT-EventQueue-0"
/opt/jruby/lib/ruby/gems/1.8/gems/net-ssh-2.0.3/lib/net/ssh/transport/ke

this is just after :

i think here net/ssh makes use of OpenSSL (even if I didn't require it)

which dislike ssh-dss for host-key.

the better, for me, would be to avoid using OpenSSL but i don't know how
to...

also, at the beginning i had only a dsa pair and, because of that prob
I've genrerated a rsa one.

no change.

also I've renammed the known_hosts file in order to generate another one
with this new rsa key.

abviously, no change ...
