Never heard of it. Why do you need an app to download wallpapers in the first place?

I don’t see how you’d have any less problems with a natively installed Node.js, Python or PHP application. This is not a Java specific issue.

Ok, that I can understand. But any modern Java application should be shipped as a container were this isn’t an issue.

Not sure what experience with Java you are talking about. As a Dev, modern Java still rock solid and is finally quite convenient to use and the JVM itself is a great runtime.
