OK, I tried it and I get the same behavior.  BTW, this is what I mean 
when I ask "show us the command line":


C:\Users\Brenden\Dev\proj\hw\dist>hw.jar

C:\Users\Brenden\Dev\proj\hw\dist>java -jar hw.jar
Hello world!

C:\Users\Brenden\Dev\proj\hw\dist>

That's cut-and-paste directly from my window on my computer.  It's easy 
to do, saves typing, and most importantly avoids typos when you're 
trying to ask a technical question.  Learn how to do it (use Google).

So I tried it with a new GUI app I made (just shows a dialog box with 
"Hello World!") and that displays the dialog, but there's still no 
console output.  So I'm sure I have the file association set, and 
further I'm still seeing the same behavior as you.  I'm guessing this is 
Microsoft interacting poorly with other vendors' products, and leave it 
at that.  File a bug report if you believe that will help.  Meanwhile, 
just use the "java -jar" command like I did above.

For others who might like to test this, here is the GUI test version:


package hwgui;

import javax.swing.JOptionPane;
import javax.swing.SwingUtilities;

/**
  *
  * @author Brenden
  */
public class Hwgui
{
    public static void main( String[] args )
    {
       SwingUtilities.invokeLater( new Runnable()
       {
          public void run()
          {
             JOptionPane.showMessageDialog( null, "Hello World!");
          }
       } );
       System.out.println( "Hello World!" );
    }
}
