We are moving from Payara 4 to 5 and it seems the @Transient annotation is not working as expected. We get the below MyDTO from a resultset, make some calculations and set myField. Somehow EclipseLink tries to updated the myField when the transaction closes eventhough it has the @Transient annotation.

import javax.persistence.*;

@Entity
public class MyDTO implements Serializable, MyInterface {

    @Id
    ...

    private MyField myField;

    @Transient
    public MyField getMyField() {
        return myField;
    }

    @Override
    public void setMyField(final MyField myField) {
        this.myField = myField;
    }

    ...

}

This is the error that get:
Caused by: org.postgresql.util.PSQLException: ERROR: relation "mydto" does not exist
