When you use JPA criteria API, the numeric value are not binded but are directly set in the SQL instead. 

eq: you have a generated SQL like:
select ... from ... where age=12;
instead of 
select ... from ... where age=?;
With '12' as parameter.  

when you test the following code:

{code:java}
@Entity
public class User {
	@Id
	private int id;

	private int age;
        ...
}
{code}

{code:java}
    CriteriaBuilder builder=em.getCriteriaBuilder();
    CriteriaQuery<User> query=builder.createQuery(User.class);
    Root<User> root=query.from(User.class);
    query.select(root).where(builder.equal(root.get("age"),12));
    em.createQuery(query).getResultList();
{code}
