-----------------------------
SSHD-78 looks like no patch.
So how to fix the issue?

> I followed the tutorial at http://mina.apache.org/sshd/embedding-sshd-in-5-minutes.html to create a basic sshd application. As in the example, I am using SimpleGeneratorHostKeyProvider to provide the server identity. I am allowing SimpleGeneratorHostKeyProvider to generate its own key file. However when it tries to read its own output file, it fails and generates a new key. This means that ever time the server is restarted the file is generated again, so clients must remove the old entry from their known_hosts file.
