The Demo hangs on the attempt to close third and subsequnt internal
frames. The endless loop is a while loop in
JComponent.paintChildrenWithOverlap: if the component is not visible,
the component index is not advanced forward. The patch replaces the
while loop with the for loop that seems more appropriate in this case.
