The latest versions of JSCH 0.1.49 and 0.1.50 are having issues transferring
larger files (I'm testing with ~400MB) to ProFTPD server, however, the older
version 0.1.44 that I've tested works (and has been working) just fine for
quite some time. I've included the configuration information of ProFTPd below.
The transfer of the file usually hangs anywhere between 10% and 20% of the
transfer and is reproducible 100% of the time (for me) using the Sftp.java
example class to upload the file using jsch version 1.49 and 1.50. Jsch
version 1.44, it works every time.
I have the following setting configured in my proftpd config as recommended by
the link below.
SFTPClientMatch ".*JSCH.*" channelWindowSize 1GB

Can you please explain what change would have affected this and what
adjustments I can make in the short term to get this transfer working?
