Can javax.persistence.Query.getResultList() return null?

Question

And if so, under what circumstances?

Javadoc and JPA spec says nothing.

Answer 1

Contrary to Arthur's post, when I actually ran a query which no entities matched I got an empty list, not null. This is using Hibernate and is what I consider correct behaviour: an empty list is the correct answer when you ask for a collection of entities and there aren't any.
