Invalid algorithm identifier

[zMcKracken]

Hello,
I'm using your cool lib to connect to several SFTP server and it works fine, never had a problem.
Now I have to connect to a WINDOWS AXWAY MFT, and doing the same thing as the other connection, it does not work.
I asked for a log to the counterpart and they say that the logs show "Signature verification request with an invalid algorithm identifier (0(unknown))".
My log is:

UPDATE:

I try another lib jsch and I had the same problem, but it seems my couterpart use ssh-rsa for server host key and pubkey accepted algorithms so adding this fix the problem.
The code is:

jschSession.setConfig("server_host_key", "ssh-rsa," + jschSession.getConfig("server_host_key"));
        jschSession.setConfig("PubkeyAcceptedAlgorithms", "ssh-rsa,ssh-dss," + jschSession.getConfig("PubkeyAcceptedAlgorithms"))
```;



I'm wondering if there is a similiar thing in sshj or a way to prioritize  ssh-rsa in the list
