On Hibernate 5 I receive the following warning: deprecation: HHH90000016: Found use of deprecated 'collection property' syntax in HQL/JPQL query [null.elements]; use collection function syntax instead [elements(null)].

Example Query:

List<Book> books = session.createQuery(
"from Book b where :x member of b.bookCategories")
.setParameter("x", crimeStory)
.list();

There is a stackoverflow that mentions this issue: http://stackoverflow.com/questions/33338186/how-to-remove-hibernate-deprecation-warning-message

Now this issue does not occur if you are using the INNER JOIN syntax.
