Thomas Wolf reopened SSHD-1310:
-------------------------------
      Assignee: Thomas Wolf

Re-opening.

Actually, yes, an {{SftpFileSystem}} is intended to be used in a session. But 
there are two cases:

# The {{SftpFileSystemProvider}} provides the file system. In that case, the 
session created by the {{SftpFileSystemProvider}} is owned by the 
{{SftpFileSystem}} and _must_ be closed when the file system is closed.
# Client code has already a {{ClientSession}} and creates the file system 
directly via {{SftpClientFactory.instance().createSftpFileSystem()}}. In that 
case the session _must not_ be closed when the {{SftpFileSystem}} is closed.

> SftpFileSystem.close() method, closes the session as well.

> SftpFileSystem.close() method, closes the session as well. 
> We expect only the sftpfilesystem channel to be closed.  Since we use the 
> same session for multiple operations (exec command, SFTP download & upload, 
> SFTP client list directory). 
>  
> SftpFileSystem.java 
>     public void close() throws IOException {
>         if (this.isOpen()) {
>             SftpFileSystemProvider provider = this.provider();
>             String fsId = this.getId();
>             SftpFileSystem fs = provider.removeFileSystem(fsId);
>             ClientSession session = this.getClientSession();
>             *session.close(true);*
>             if (fs != null && fs != this) {
>                 throw new FileSystemException(fsId, fsId, "Mismatched FS 
> instance for id=" + fsId);
>             }
>         }

> can you please check and let us know, if this can be fixed  ?
