Gary D. Gregory commented on NET-712:
-------------------------------------

If you want anyone to look at this here, I think you'll need to provide a failing test, preferably as PR on GitHub.

> If I try to upload images (tested with PNG and JPEG), the images are not correctly stored on the server. Instead, they are missing one byte. Two examples:
>  # The original file had a size of 35518 bytes, once I transferred it using FTPClient it were 35517 bytes.
>  # The original file had a size of 45010 bytes, once I transferred it using FTPClient it were 45009 bytes.
> Using a PNG breaks the image completely (viewers can't view it), using a JPEG makes the photo still viewable, but the files are different (in size/MD5 fingerprint).
> This affects all PNG and JPEG files, but any other file works. They have the same size and MD5 fingerprint.
> Maybe related to https://issues.apache.org/jira/browse/NET-409 which was fixed in 3.0.1, but this occurs on 3.8.0.
>  
> This can be reproduced on Android using FTPClient in an app and on "regular" JVM (for me OpenJDK 17). The Kotlin file I attached provides a simple example, but it doesn't contain something special. I executed it using Gradle (to add NET as dependency) and using IntelliJ's build and run system.
