> 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 "***".

> But SftpFileSystem actually got an exception from JSch that it did not set as cause for
the newly created exception, making debugging harder.
