>> Please review a fix for jdk16.
>> On macOS 11 (bigsur), using the Swing Aqua Look and Feel, the text of the selected JTabbedPane tab title text is just a light gray outline of white text on a white background. The macOS 11 design inverted from dark background / light text to light background / dark text, so white text on white background is not legible.
>> Correct system color to use for this scenario, as per Apple, is [NSColor controlTextColor]
>> so the proposed fix is to use this system color for BigSur. 
>> For preBigSur releases, "white" is still used as the above color is for text color but the tabPane background color is still not readable through any Apple API, so [NSColor controlTextColor] which returns black will not be legible on preBigSur releases which has black background.
