Description
I'm encountering an issue with the Alpakka library which uses sshj for the SFTP implementation. I started encountering net.schmizz.sshj.sftp.SFTPException: EOF while reading packet errors on very specific XML files where files are embedded (EDI use-case).
I've created some tests where I specifically use the sshj library for the SFTP actions and am able to replicate the issue with a locally hosted SFTP server and the file.
Due to the sensitive nature of the documents i am not able to share those, I have not been able to manually reproduce a document where the issue occurs.
This is the test i've created (Scala code) where I've tested our abstracted client, the Alpakka client and then the sshj library.
I have a workaround in the test Should upload file with sshj where i create a temporary file on the system to then use the put function (I suppose it does a full copy instead of a streamed write).
