Read about toFront in the API http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Window.html#toFront

Some platforms may not permit this VM to place its Windows above windows of native applications, or Windows of other VMs.

On Windows OS for example toFront causes the icon on the Task Bar to flicker, but the window stays in the back.
