        private List locations;

Answer 1

The key phrase in Pascal's reply is

the target objects cannot be queried, persisted, merged independently of their parent object

As you are dependent on the parent object, you should be able to do this using something like ...

SELECT p FROM PERSON, IN (p.locations) WHERE p.id = ?1 AND locations = ?2

(Based on the reply at Execute "MEMBER OF" query against 'ElementCollection' Map fields in JP-QL (JPA 2.0) - which is actually a Map @ElementCollection which was what I was looking for an answer to!)
