Bug Description: 
  Launching a modal dialog in processFocusEvent makes application hang.

Steps to Reproduce (be specific):
  Run the following program. When focus is moved away from the frame, 
  the dialog launches and the application just hangs. If you try to the 
  same thing in processMouseEvent, it works well.

Test program:(Test.java):

import javax.swing.event.*;

public class Test {

    public static void main(String[] args) {
        final JFrame f = new JFrame();
        JTextField t = new JTextField("TEST") {
            { enableEvents(AWTEvent.FOCUS_EVENT_MASK
                         | AWTEvent.MOUSE_EVENT_MASK); }
            protected void processFocusEvent(FocusEvent e) {
                super.processFocusEvent(e);
                if (e.getID() == FocusEvent.FOCUS_LOST) {
                    JOptionPane.showMessageDialog(f, "Check");
                }
            }
            protected void processMouseEvent(MouseEvent e) {
                super.processMouseEvent(e);
//                JOptionPane.showMessageDialog(f, "Check");
            }
        };
        f.getContentPane().add(t);
        f.setBounds(100, 100, 200, 200);
        f.show();
    }
