I went on to test Jetpack Desktop on my Raspberry. Now I don’t have my app exported to a .deb file because it’s still far from being a functional app so I tried to compile it from IntelliJ and after waiting a long long time for a Gradle build the app itself could never successfully compile, so I can’t tell how it works when compiled from IntelliJ.
I’m going to eventually export my little app to a .deb file and will then tell you if it runs but that is going to be two weeks to a month from now because I have other duties to tend to before finishing the app.
Also, JVM stuff, at least PyCharm and IntelliJ Idea seem to run a bit sluggishly on the Pi. The sluggishness in PyCharm was improved by overclocking the Raspberry Pi to 1750Mhz but not fully resolved.
