qwerty287 updated NET-712:
--------------------------
Environment: Android and Manjaro, running in IntelliJ with Gradle and
OpenJDK 17 (was: In production (where the bug was noticed), FTPClient runs on
Android, installed was NET with Gradle.
To reproduce, I created a simple file (attached below) in Kotlin which I ran
using Gradle and IntelliJ's builtin Kotlin compiler and JVM (OpenJDK 17).)
> Image are not uploaded correctly
> --------------------------------
>
> Key: NET-712
> URL: https://issues.apache.org/jira/browse/NET-712
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 3.8.0
> Environment: Android and Manjaro, running in IntelliJ with Gradle and
> OpenJDK 17
> Reporter: qwerty287
> Priority: Major
> Attachments: FTPImageExample.kt
>
>
> 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.
