I am trying something in the lines of:
    SELECT inst
    FROM   instelling inst
    JOIN FETCH inst.aanvragen
    JOIN FETCH inst.aanvragen.beoordelingen

But the problem is that the field aanvragen is a list. So I get:
    JPQL does not allow traversal through multi-valued relation path.
    Try join instead.

I would like the JOIN to take place on the max value of aanvragen. Is
this possible? If so: how?
