    public class JGitClientSession
extends org.apache.sshd.client.session.ClientSessionImpl
    A ClientSession that can be associated with the HostConfigEntry the session was created for. The JGitSshClient creates such sessions and sets this association.

    Also provides for associating a JGit CredentialsProvider with a session.

        Reads the RFC 4253, section 4.2 protocol version identification. The Apache MINA sshd default implementation checks for NUL bytes also in any preceding lines, whereas RFC 4253 requires such a check only for the actual identification string starting with "SSH-". Likewise, the 255 character limit exists only for the identification string, not for the preceding lines. CR-LF handling is also relaxed.
        Overrides:
        doReadIdentification in class org.apache.sshd.common.session.helpers.SessionHelper
        Parameters:
        buffer - to read from
        server - whether we're an SSH server (should always be false)
        Returns:
        the lines read, with the server identification line last, or null if no identification line was found and more bytes are needed
        Throws:
        StreamCorruptedException - if the identification is malformed
