The current fix works for the cases listed in the test but fails for the following scenarios. To make the test more stable it is better to reassign the static variable `lastFrameState = Frame.NORMAL` in examineStates after creating a new Frame [here ](https://github.com/openjdk/jdk/blob/57b8251241e2044d5039ce162bf4637a9b2e5466/test/jdk/java/awt/Frame/MaximizedToIconified/MaximizedToIconified.java#L78), so that each time a new case is run it sets lastFrameState to default state.


// CASE 1:
examineStates(new int[] {Frame.NORMAL, Frame.MAXIMIZED_BOTH, Frame.ICONIFIED});
// CASE 2:
examineStates(new int[] {Frame.NORMAL, Frame.ICONIFIED, Frame.MAXIMIZED_BOTH});
