wallpaperdownloader (stable) 2.1 from 'egarcia' installed

Name=WallpaperDownloader V2.1

Exec=java -jar -Duser.home=/home/vasilisc/snap/wallpaperdownloader/3

"Exec=java -jar -Duser.home=/home/vasilisc/snap/wallpaperdownloader/3 
/snap/wallpaperdownloader/3/jar/wallpaperdownloader.jar"

If Java is not installed on your system, then you have a problem. 
"Exec=java" - It's not right.

For example, my script-wrapper can do the useful steps BEFORE start of 
the java program.
