Changes requested by prr (Reviewer).

Read the comment in https://github.com/openjdk/jdk/pull/9825.
This PR needs to be merged into that PR and this PR withdrawn.
Bugs should be closed as dups.

I don't intend to do a detailed review of this PR until the content is merged into the other one.

src/java.desktop/share/classes/javax/swing/text/html/CSS.java line 1458:

> 1456:      * </a> specifications.
> 1457:      * By example <code>rgb(rc gc bc)</code>,
> 1458:      * <code>rgb(rc,gc,bc)</code>, <code>rgb(rc gc bc / ac)</code>,

For many years javadoc has preferred {@code rgb(rc,gc,bc)} instead of <code> .... </code>

Since this comment is being updated existing and new cases should be converted.
