I have added a WindowStateListener to a frame. I am setting the state of the frame to 'MAXIMIZED_BOTH' and the frame gets maximized. Then I am calling setExtendedState(Frame.ICONIFIED) and the frame gets iconified. When this is executed on WinXP, the sequence of window state events triggered is as follows:

======= From Listener - Win XP =======================
OLD state: NORMAL
New state: MAXIMIZED_BOTH MAXIMIZED_VERT MAXIMIZED_HORIZ

OLD state: MAXIMIZED_BOTH MAXIMIZED_VERT MAXIMIZED_HORIZ
New state: MAXIMIZED_BOTH MAXIMIZED_VERT MAXIMIZED_HORIZ ICONIFIED
==============================================

The same application on solaris triggers the following sequence of events:
======= From Listener - Solaris 9 (GNOME2.0) =======
OLD state: NORMAL
New state: MAXIMIZED_BOTH MAXIMIZED_VERT MAXIMIZED_HORIZ

OLD state: MAXIMIZED_BOTH MAXIMIZED_VERT MAXIMIZED_HORIZ
New state: ICONIFIED
==============================================

I feel the event sequence triggered by WinXP is correct. Actually when iconifying a frame which is in maximized state, the new State should typically be MAXIMIZED + ICONIFIED. But on Solaris, it shows as 'ICONIFIED'.

Moreover, I tried executing this multiple times on Tiger as well as previous releases and the results seem to be inconsistant. I am surprised to get the same behavior as WinXP quite a few times on the previous releases (1.4) though i didn't get even once on Tiger - b32.

I have attached a sample testcase. Execute the sample testcase. If you get the results as mentioned above, then the bug is reproduced.

I tested this on Solaris Sparc 9 with GNOME2.0 desktop.
