Code seems to break at session.connect.

com.jcraft.jsch.JSchException: Session.connect: java.io.IOException: End of IO Stream Read

Stacktrace

Code

try {
    JSch jsch = new JSch();
    Session session = null;
    session = jsch.getSession(ftpUserName, ftpServer, 22);
    session.setClientVersion("StrictHostKeyChecking");
    //session.setConfig("StrictHostKeyChecking", "no");
    session.setPassword(ftpPassword);
    session.connect();

    Channel channel = session.openChannel("sftp");
    channel.connect();

} catch (Exception e) {

回答1:

There was an interoperability problem with older versions of Jsch (e.g. 0.1.52) and recent versions of openssh (e.g OpenSSH_7.2p2). The problem went away for me after upgrading to Jsch 0.1.54.
