System Tray, clean transition?

On minimize, I set my JFrame's visibility to false, I have an actionlistener set up so when I double click the process in the System Tray, the JFrame because visible again. The only problem is that when I reset it to visible, it kind of just flashes on the screen. Is there a way I can make the JFrame kind of just 'UN-minimize' instead of just flashing on?

Here is the VERY simple code I am using:

Java Code:

if (e.getSource().equals(displayMenu) || e.getSource().equals(icon)) {
                frame.setVisible(true);
                frame.setState(JFrame.NORMAL);
            }
