Keylistener registers 1 second later

Question

A keylistener that I put on a jframe is delaying around 1 second, when it should be near instant. I'm fairly certain this is a linux/crouton issue, because the code works fine on a windows system.

public void initComponents(){
  JFrame frame = new JFrame("test");
  frame.getContentPane().addKeyListener(new KeyListener(){
    public void keyPressed(KeyEvent e){
      System.out.println(e.getKeyChar());
    }

    public void keyReleased(KeyEvent e){
    }

    public void keyTyped(KeyEvent e){
    }
  })

  frame.setSize(500, 300);
  frame.setVisible(true);

}
