Eclipselink 2.7: using NULLS [FIRST|LAST] in Criteria API

Question

i am trying to build a simple <script src="https://unpkg.com/vue@2.5.10/dist/vue.min.js"></script> <div id="app"> <input type="text" v-model="myid" placeholder="My ID" /> <button type="button" @click="click">Submit</button> </div> using the Eclipselink Criteria-Api. All available answers here fit the Hibernate-Implementation or NULLS LAST in JPQL. Since "NULLS LAST" works when specifying it in the JPQL-String, i really need the Criteria-solution, because this query is "very dynamic".

I found the class OrderByItem which has related constants, but i can't figure out how this class may be used:

http://www.eclipse.org/eclipselink/api/2.6/org/eclipse/persistence/jpa/jpql/parser/OrderByItem.html

ORDER BY hitCount DESC|ASC NULLS LAST

Thanks in advance!
