ADDITIONAL SYSTEM INFORMATION :
Manjaro / KDE / Java 17

A DESCRIPTION OF THE PROBLEM :
Drag-n-Drop of files that contain [ or ] does not work on Linux / KDE because KDE applications such as the Dolphin File Manager. Because KDE applications do not URI-encode the [ and ] character when passing uri-list-flavor text data, but the Java DnD internals don't gracefully handle these slightly-off-spec URIs, and instead fails.

Test File Path:

"/home/rednoah/Downloads/Hello World [test].txt"

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create basic Java GUI application that accepts java-file-list-flavor drop data and then drop a file that contains [ or ] from KDE / Dolphin File Manager.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Files with [] in the file path should work just like any other file path.

FREQUENCY : always
