java.awt.TextComponent does not use SystemColor.window
as the background color when specified on Windows 95/NT.
To reproduce this problem, you must set your Windows
Display colors so that a non-White color is used for
"Window Text". For example, if you set your "Window Text"
color to be gray, and run the example application below,
you will see that the java.awt.Label's will have a
gray background, but the TextField and TextArea will
have a white background.
