The @hidden tag is supposed to hide program elements in generated API documentation. However, support for @hidden tags in classes and interfaces is currently incomplete. While page generation for hidden types itself is suppressed, these types show up in several places in the generated documentation, including links to the non-existing pages.

The correct handling would be to not have these types show up in the documentation at all. If a member of a hidden class that is not itself hidden shows up as a documented member in a non-hidden class it should be displayed as a member of that non-hidden class, similar to the way it is done for members of private/package private classes.
