ADDITIONAL SYSTEM INFORMATION :
Mac OS Big Sur

A DESCRIPTION OF THE PROBLEM :
If I use a Swing JTabbedPane on Mac OS Big Sur the foreground of the selected tab text is white and the background is also white thus it's very hard to read the tab text.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JTabbedPane with several tabs inside.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The selected tab text should be easily readable.
ACTUAL -
The selected tab text cannot be read easily as it is written with white on a white background.
