    // Linux:
    // The frame comes up with the textArea visible (a blinking
    // cursor can be seen).

    // Mac before JDK-8139208
    // The frame comes up and minimizes immediately.
    // After deminimizing by the user the textArea is visible
    // (a blinking cursor can be seen).
    //
    // Mac after JDK-8139208
    // The frame comes up with the textArea NOT visible. It does
    // not minimize automatically.
    // Minimizing and deminimizing by the user makes the textArea
    // visible (a blinking cursor can be seen).
    //

    // Only a minimized icon in the taskbar gets visible.
    // Deminimizing this by the user makes the textArea
    // visible.
