The JPQL UPDATE query UPDATE Person SET firstName=:newFirstName WHERE id(this)=:ssn which optionally omits the entity identification variable (for consistency with JDQL) gets NullPointerException out of EclipseLink.

I could recreate the issue.

Below is the Person entity we have by referencing the entity present in Jakarta Data.

@Entity
public class Person {

    @Id
    public long ssn_id;
    public String firstName;
    public String lastName;
}

Here is the code where we executed the JPQL query:

public void testOLGH28908() throws Exception {
        Person p = new Person();
        p.firstName = "John";
        p.lastName = "Jacobs";
        p.ssn_id = 111111111l;

        Person result;

        tx.begin();

        try {
            em.persist(p);

            em.createQuery("UPDATE Person SET firstName=:newFirstName WHERE id(this)=:ssn")
                            .setParameter("newFirstName", "Jack")
                            .setParameter("ssn", p.ssn_id)
                            .executeUpdate();

            result = em.createQuery("SELECT Person WHERE ssn_id=:ssn", Person.class)
                            .setParameter("ssn", p.ssn_id)
                            .getSingleResult();

            tx.commit();
        } catch (Exception e) {
            tx.rollback();

            throw e;
        }

This resulted in the following exception stack, which is the same as described in the issue:

Maybe try latest snapshot from https://jakarta.oss.sonatype.org/content/groups/staging/org/eclipse/persistence/eclipselink/5.0.0-SNAPSHOT/ which contains #2224 .

We checked with latest snapshot, but the test is still failing.
