I'm using jpackage to build a Mac dmg installer for my application.
On Mojave, the generated dmg looks great, it has a nice icon and background image showing the user they need to drag the app to the Applications folder:
On Big Sur, the background image is gone and the application icon looks like a folder:
Bad UX. I'm using the same jdk (jdk-16.0.2.jdk) and switches on both OSes.
Anyone else run into this issue?
