>            Reporter: Ray Tsang
>            Assignee: Adrian Nistor
>            Priority: Minor
>             Fix For: 9.0.0.Beta1, 9.0.0.Final

> In example for Books in https://docs.jboss.org/author/display/ISPN/Querying+Infinispan
> ~~ snip snip ~~
> CacheQuery query = searchManager.getQuery(luceneQuery, Book.class); 
> // and there are your results!
> List<Book> objectList = query.list();
> ~~ snip snip ~~
> This doesn't actually work.  CacheQuery.list() returns List<Object>
> Thus, you will need to cast: List<Book> books = (List<Book>) cq.list();
> But this wouldn't work... Instead you'll end up doing: List<Book> books = (List<Book>)(List<?>) cq.list();
