[JSch-users] "Failure" exception in ChannelSftp._realpath()

[Danisment G. U. <du...@ub...>]

Hello,

JSch: 0.1.49/0.1.50
SSH Server: freeSSHd 1.2.4 on Windows

I got an exception with just "Failure" message. This is stack trace:

This is the code of ChannelSftp._realpath:
******************************************
  private byte[] _realpath(String path) throws SftpException, IOException,
Exception{
    sendREALPATH(Util.str2byte(path, fEncoding));

    Header header=new Header();
    header=header(buf, header);
    int length=header.length;
    int type=header.type;

    fill(buf, length);

    if(type!=SSH_FXP_STATUS && type!=SSH_FXP_NAME){
      throw new SftpException(SSH_FX_FAILURE, "");
    }
    int i;
    if(type==SSH_FXP_STATUS){
      i=buf.getInt();
      throwStatusError(buf, i); <--- THIS IS LINE 2160 FROM WHICH EXCEPTION
IS THROWN.
    }
    i=buf.getInt();   // count

    byte[] str=null;
    while(i-->0){
      str=buf.getString();  // absolute path;
      if(server_version<=3){
        byte[] lname=buf.getString();  // long filename
      }
      SftpATTRS attr=SftpATTRS.getATTR(buf);  // dummy attribute
    }
    return str;
  }

As I understand if type is SSH_FXP_STATUS, this problem occurs.

What does this probleam mean ? How can I solve it ?

thanks in advance.
