The desktop entry point is an ordered list

Desktop. Most of what follows is only correct because of where it sits — treat the entry function as a sequence, not a bag of setup calls.

// adapted — order is load-bearing top to bottom
fun main(args: Array<String>) {
    forceLinuxWmClass()      // 5. the launcher's first statement — it builds the toolkit itself
    runDesktopApp(args)
}

fun runDesktopApp(args: Array<String>) {
    CrashDialog.install()                    // 1. catch everything from here on

    java.awt.Desktop.isDesktopSupported()    // 2. probe BEFORE any native loads
