Minimized JInternalFrame icons appear in incorrect positions if the main frame is resized

OPERATING SYSTEM(S):
--------------------
Red Hat Linux / Windows

FULL JDK VERSION(S):
-------------------
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode)

DESCRIPTION:
------------
Steps to Recreate:

1. Launch SwingSet2.jar
2. Select JIntarnalFrame demo
3. Minimize one of the internal frames. It will become an icon located
   in the lower left corner of the main frame
4. Maximize main frame

    => Problem: Location of minimized icon in InternalFrame does not
                follow resized main frame - it is no longer at the
                bottom left of the main frame

    => Expected result: Location of icon in InternalFrame should follow
                        resized main frame and remain in the lower left
                        corner

5. Un-minimize internal frame to restore it to its original size
6. Un-maximize main frame to restore it to its original size
7. Minimize internal frame again

    => Problem: Internal frame is not minimized to the lower left of
                the main frame.

    => Expected result: Internal frame should be minimized to an icon
                        located in the lower left of the screen
