How to make runnable Jar programs that do not fail silently?

Question

For the runnable Jar programs I create, I can read the unhandled exceptions if I run it from the command prompt (java -jar myprogram.jar).

Example code:

public static void main(String args[]) {
    try {
        EntireProgram();
    } catch (Throwable t) {
        throw new Error("somehow our error handling code has errors");
    }
}

public static void EntireProgram() {
    System.out.println(1 / 0);
}

Command line output:

However, if I run the Jar program by double-clicking it (expected of most end-users), the unhandled exceptions stay silent. I've noticed that this is in contrast to "native Windows programs" which I believe have unhandled exceptions handled by the OS default handler (modal dialog message):

The advantage of handling unhandled exceptions this way is that the user will know something wrong has happened (and perhaps report it, hopefully).

How can I make my program's unhandled exceptions be handled in such a way?

Why don't you add a single line like this in your catch block ..which will show you the error message irrespective of How you run your app.

javax.swing.JOptionPane.showMessageDialog(null,"Something is really wrong..Hence notifying you..");
