Remedy

From the maintainer: For Apache MINA SSHD <= 2.9.1, do not use org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider to generate and later load your server's host key. Use separately generated host key files, for instance in OpenSSH format, and load them via a org.apache.sshd.common.keyprovider.FileKeyPairProvider instead. Or use a custom implementation instead of SimpleGeneratorHostKeyProvider that uses the OpenSSH format for storing and loading the host key (via classes OpenSSHKeyPairResourceWriter and OpenSSHKeyPairResourceParser).
