Solution 1: Tested on Windows

I used a JFrame for the modal window

JFrame mainWindow = new JFrame;
mainWindow.setVisible(true);
JFrame modalWindow = new JFrame();
// The next two sentences gives modalWindow modal beahaviour
mainWindow.setEnabled(false);
mainWindow.setFocusable(false);
modalWindow.setVisible(true);

Solution 2: Tested on Ubuntu

I added a WindowFocusListener

addWindowFocusListener(new java.awt.event.WindowFocusListener() {
    public void windowGainedFocus(java.awt.event.WindowEvent evt) {}
    public void windowLostFocus(java.awt.event.WindowEvent evt) {
        formWindowLostFocus(evt);}

private void formWindowLostFocus(java.awt.event.WindowEvent evt) {
    this.requestFocus();
    this.toFront();}
