Simple Java 2D game - resuming the game

I am writing a simple Java game and have ran into some problems while adding the pause/resume functionality.

My main game loop looks like this:

    @Override
    public void run() {
        try {

        while (true) {
            if (!isPaused) {
                Thread.currentThread().sleep(5);
                diamondSpawner();
                collisionDetector();
                repaint();
            } else {

            }
        }
    } catch (InterruptedException e) {
    }
}

Additionally, I have added a KeyListener to the main class, which waits for the user to press 'P' to pause the game. Unfortunately, the problem is that the KeyListener doesn't listen to the keys while in the state of being paused. How can I make it listen?

This is the KeyListener in the main classes' constructor:

this.addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent evt) {
                if (evt.getKeyCode() == KeyEvent.VK_P) {
                    isPaused = !isPaused;
                }
                helicopter.move(evt);
            }
        });

MadProgrammer solved my problem. Just make the variable isPaused volatile. Thanks!
