JSch 0.1.53 session.connect() throws “Fin de IO Flux Lire”

J'ai téléchargé une nouvelle JSch 0.1.53 bibliothèque et JSch (sftp) la tâche de téléchargement ne fonctionne plus. Cette version échoue sur session.connect() fonction de lancer une erreur Session.connect: java.io.IOException: End of IO Stream Read.

Mon vieux jsch.jar(2011-10-06) fonctionne très bien sur le même hôte, peut-être que je suis absent une nouvelle config accessoires?

Session session=null;
ChannelSftp channel=null;
try {
    JSch.setLogger(SSHUtil.createJschLogger());

    JSch jsch=new JSch();
    session=jsch.getSession("myuser", "11.22.33.44", 22);
    session.setConfig("StrictHostKeyChecking", "no"); 
    session.setPassword("mypwd");
    session.connect(2000); //<-- FAILS HERE
    channel = (ChannelSftp)session.openChannel("sftp");
    channel.connect(2000);
    ...

C'est un vaste JSch journalisation indiquant ce qui se passe.

J'ai aussi un très vieux Jsch.jar (2011-10-06) où la tâche de téléchargement fonctionne très bien, c'est un journal. Une Raison pour laquelle je voulais mettre à jour est très lent transfert de fichiers. Nouvelle version devrait mieux faire les choses que j'ai lu.

MODIFIER
J'ai eu une idée pour backstep communiqués dans un Repository Maven et en fait c'est cette nouvelle version ne fonctionne pas correctement. Précédente jsch-0.1.52.jar version fonctionne très bien. J'essaie de contacter la bibliothèque de développeurs.

C'est un journal à partir d'un travail 0.1.52 libération.

Vous êtes probablement se déconnecté par le serveur. Quel est le journal du serveur de dire?
Les bons points, ajouté 0.1.52 journal, la nouvelle(à défaut) communiqué de presse est 0.1.53.jar fichier. Vidage du journal imprime une version de bibliothèque dans le début.
Ne pas utiliser StrictHostKeyChecking=no, vous sont en train de perdre la protection contre les attaques de type MITM en le faisant.
