A DESCRIPTION OF THE PROBLEM :
In the Swing HTML package, we can't use most of the named colors from the CSS 4 Level recommendation. https://www.w3.org/TR/2022/CR-css-color-4-20220705/#named-colors.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Test the provided program with :
- JDK without patch.
- JDK patched (PR https://github.com/openjdk/jdk/pull/9825)
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
With the patch, the two texts must be the same color cyan.
ACTUAL -
Without the patch, the first text is blakck, the second text is cyan.
