These are the `Could not find any member to link for "..."` errors mentioned above. The syntax looks fine but as far as I can tell it complained and could not link to anything in a different module. But even that doesn't explain all of it. Javadoc would also generate a warning if the `@link`-ed class was not on the classpath. Better would be to make the link work if possible; I am not sure how to fix that. This generates the same (lack of) links and doesn't have a warning, at least.
