Hi for all,

I have started project with EclipseLink... thats great... but, I got stackoverflow with this scenario:
Entities : ClassList, lvlupgain and skilltrees.
ClassList have a column id and it can be referenced for lvlupgain and skilltrees.
ClassList -> lvlupgain (OneToOne)
ClassList -> skilltrees (OneToMany)

RecordCount:
ClassList = 89
lvlupgain = 89
skill_trees = 13722

 public void loadData() {
        EntityManagerFactory emf;
        emf = Persistence.createEntityManagerFactory("TestRelationshipPU");
        ClassListJpaController jpa = new ClassListJpaController(emf);
        List<ClassList> listData = jpa.findClassListEntities();
        for (ClassList classList : listData) {
            System.out.println("classList" + classList.getClassName());
        }
    }

Error:

Include more of the stack trace.

Are you using LAZY relationships, does the error occur if you do?

Include your code for the classes. Have you mapped the Id correctly, what cache type are you using?
