I think the problem is that the first state change (uniconify) causes a native event that changes the frame's state, but that event isn't delivered until after the second state change (maximize) occurs, which is causing problems on the final state of the frame. The displayChanged call between these state changes was intended to flush the native event queue and cause the event to be delivered between the state changes.
