I don't code in any of these platforms, so I'm asking genuinely.

When this community talks about cross-platform desktop applications, they typically mean Electron, Tauri, or other similar web-based desktop apps. All of which are less than ideal for various reasons.

Java apps have been cross-platform since well before it was cool. I've heard a lot of positive things about Kotlin. It's also kinda-sorta native, I think? So why does it seem Java-based cross-platform apps are rarely mentioned in these discussions?

I know the negative aspects of the web-based desktop apps (bundle size, speed, etc). What are the negative aspects of a Java-based app?
