It should work, but looks like it doesn't :) but to be fair this is feature added in latest version of check style.

from docs:
> processJavadoc
> Optionally: it is referenced in Javadoc comments. This check is off by default, as it is considered bad practice to introduce a compile time dependency for documentation purposes only. As an example, the import java.util.Date would be considered referenced with the Javadoc comment {@link Date}. The alternative to avoid introducing a compile time dependency would be to write the Javadoc comment as {@link java.util.Date}. 

My personal opinion is that javadocs should introduce compile time dependency...
