Exception when trying to upload to directory

Hi,

I am getting the following exception when trying to upload to a directory.

java.io.IOException: Trying to upload file test.txt to path WBAFZTXA-SIT/test.txt but that is a directory
at net.schmizz.sshj.sftp.SFTPFileTransfer$Uploader.prepareFile(SFTPFileTransfer.java:297)

test.txt is a file, but the error message says that it is a directory. Is this because the source directory could be a virtual directory ?

Thanks.
Meena.
