Removing an element from the middle (not first, not last) of a @ElementCollection with @OrderColumn hangs up EclipseLink.

Reproducible: Always

Steps to Reproduce:
1. Create entititeies


@Entity
public class Person {
	@Id
	@GeneratedValue(strategy=GenerationType.TABLE)
	private int id;

	@Basic
	private String name;

	@ElementCollection
	@CollectionTable(
	        name="PERSON_LOGIN",
	        joinColumns=@JoinColumn(name="PERS_ID", referencedColumnName="ID")
	  )
	@OrderColumn(name="ORDER_COL")
	private List<PersonLogin> logins = new Vector<PersonLogin>();

//...
}

@Embeddable
public class PersonLogin {

	@Basic
	private String username;

	@Basic
	private String password;
//...
}


2. Add the person

		Person p = new Person();
		p.setName("Igor");
		p.getLogins().add(new PersonLogin("igor1", null, 4));
		p.getLogins().add(new PersonLogin("igor2", "pass2", 3));
		p.getLogins().add(new PersonLogin("igor3", "pass3", 2));
		p.getLogins().add(new PersonLogin("igor4", "pass4", 1));

		logStep("inserting new person...");
		em.getTransaction().begin();
		em.persist(p);
		em.getTransaction().commit();


3. Remove an element from the middle (not first, not last) will cause EclipseLink to hang up.

		em.getTransaction().begin();
		p.getLogins().remove(1);
		em.getTransaction().commit(); // it will hang up here
