      Description

        This bug is reproduced when VoiceOver is enabled and JFrame is resized such that JTabbedPane has the arrow button to navigate and focus is moved between tabs

        Step to reproduce
        -------------------------
        1) System Preference -> Accessibility -> VoiceOver -> Enable
        2) Run the SwingSet2 with -Djavax.accessibility.screen_magnifier_present=true option
        3) Once SwingSet2 Frame is visible select "Button Demo" ".
        4) Resize SwingSet2 Frame such that only one or two JTabbedPane is visible and left or right arrow is visible
        as shown in the screen recording.
        5) Observed that focus is on "Button Demo" button on the JToolBar
        6) Press tab twice so that focus is moved to "Buttons" JTabbedPane. Observe that NPE is thrown.
        If you see the same then the bug is reproduced.

        I have attached the screen shot of the same.

        This is reproduced in MacOS 13.x & 14.2. JDK 22, 21
