Back at 7u6 the Java Access Bridge was integrated into the JDK/JRE. An oversight of that effort was to not include the javadoc for the com.sun.java.accessibility.util package.

A new link and related sub-pages could be added to
http://download.java.net/jdk9/docs/technotes/guides/access/index.html

Is the fact that the package starts with com.sun going to be a problem?
If so, is there precedent as to how to manage a package name change from
com.sun.*?

Although this package name is prefixed with com.sun the earlier version of the documentation is available as follows:
- Go to Java Accessibility Utilities
    http://docs.oracle.com/cd/E17802_01/j2se/javase/technologies/accessibility/docs/jaccess-1.3/doc/
- Follow Java Accessibility Utilities Examples
    http://docs.oracle.com/cd/E17802_01/j2se/javase/technologies/accessibility/docs/jaccess-1.3/doc/examples.html
- Follow API Reference (top of page)
    http://docs.oracle.com/cd/E17802_01/j2se/javase/technologies/accessibility/docs/jaccess-1.3/doc/api/com/sun/java/accessibility/util/package-summary.html

Note that if we want the 9 pages to look like those first two 1.3 pages I'll need to spend some time to determine what is technically correct at this point in time. I also have a work item (JDK-8056925) to add at least Ferret and Monkey to 9 and the Examples page indicates other utilities, though Ferret and Monkey are the ones that are in common use.

I noticed this issue when working on
https://bugs.openjdk.java.net/browse/JDK-8044820
Consider removing externalization of GUIInitializedMulticaster and
TopLevelWindowMulticaster

I've changed those two methods from public to package-private. It looks
like just that change will ensure that javadoc doesn't get generated for
those two classes.
