The JPA CriteriaBuilder contract defines the following methods in relation to Collections:
* {{javax.persistence.criteria.CriteriaBuilder#isEmpty}}
* {{javax.persistence.criteria.CriteriaBuilder#isNotEmpty}}
* {{javax.persistence.criteria.CriteriaBuilder#size}}
But it defines no support for any of these in regards to a Map.
We should add support for these predicates against Maps to our CriteriaBuilderImpl.
