Query on entity with embeddable record fails with "A reference class must be provided"

[njr-11]

After the fix for #29117 went in, entities with an embeddable record fail further along when trying to query for the entity. EclipseLink fails with A reference class must be provided/

Entity:

 <entity class="test.jakarta.data.web.Participant">
  <table name="Participant"/>
  <attributes>
   <id name="id">
   </id>
   <embedded name="name">
    <attribute-override name="first">
     <column name="NAME_FIRST"/>
    </attribute-override>
    <attribute-override name="last">
     <column name="NAME_LAST"/>
    </attribute-override>
   </embedded>
  </attributes>
 </entity>

Class for entity and embeddable record:

public class Participant {

    public Integer id;

    public Name name;

    public static record Name(String first, String last) {
    }

    public static Participant of(String firstName, String lastName, int id) {
        Participant p = new Participant();
        p.id = id;
        p.name = new Name(firstName, lastName);
        return p;
    }
}

JPQL:

SELECT o FROM Participant o WHERE (o.name.last=?1) ORDER BY o.name.first, o.id
