We have been using the edtFtpjPro 3.1.2 jar for our SFTP requirement using the uploadFile() API of the jar and the file transfer for all file sizes have been working well for the past couple of years.
Recently, we have done a Java upgrade (from 1.6 to v1.7) on HP Unix 11.31 OS alongwith a few other upgrades.
Following the upgrade, we are facing an issue for transfer of files greater > 20 KB.
We are successfully able to transfer files with size < 20 KB. However, whenever we try sending a File > 20 KB we found that a file is getting generated at the destination with size 0 KB and no exception is reported.
I am surprised of this behaviour because it works fine with smaller files.
Appreciate if anybody could help with this issue or provide any insight.
