John Bäckstrand commented on VFS-351:
-------------------------------------
This might be a Jsch bug, partly, in that it does not seem to throw IOException
properly, instead re-throwing everything as SftpException ?
> Small patch to not swallow SFTP exception from JSCH

> A customer had a stacktrace where the end of it looked something like this:
> Caused by: org.apache.commons.vfs2.FileSystemException: Could not determine
> the type of file "***".
> at
> org.apache.commons.vfs2.provider.AbstractFileObject.getType(AbstractFileObject.java:506)
> at
> org.apache.commons.vfs2.provider.sftp.SftpFileObject.refresh(SftpFileObject.java:92)
> ... 27 more
> Caused by: org.apache.commons.vfs2.FileSystemException: Could not change to
> work directory "/".

> org.apache.commons.vfs2.provider.AbstractFileObject.getType(AbstractFileObject.java:497)
> But SftpFileSystem actually got an exception from JSch that it did not set as
> cause for the newly created exception, making debugging harder.
