Oracle reported:

** Change the labels on a MenuBar to show the effect on Solaris.
**
** Click on the Expand Button, and the MenuBar labels are changed to be longer
** such that the menu extends past the end of the bar. Click on the Shrink
** Button and the labels are made shorter. Note that the MenuBar size (one
** vs. two lines) isn't correctly adjusted.
**
** Manually resizing the window will fix up the MenuBar size and appearance.
**
** So, click on Expand. The menu labels are made longer, but no additional
** space is provided for them, so all are displayed truncated. Manually
** expand the window width (very little), and the MenuBar expands to two
** lines with fully displayed menu labels. (I saw the fourth menu item overlap
** the right edge of the MenuBar, but this was minor.) Click on Shrink.
** The menu labels are restored to their original sizes, but the menu is
** displayed, centered, in the double height MenuBar.
