This appears to be a bug but I want to be sure I am not doing something incorrect. I have the following class relationships:

public class EmbeddableData implements Serializable {

  @Column(name = "DATA_X", nullable = false)
  private double x;

  @Column(name = "DATA_Y", nullable = false)
  private double y;

public class EntityA implements Serializable {

  private static final long serialVersionUID = 1L;

  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "ID")
  private long id;

  @CollectionTable(name = "DATA_TABLE", joinColumns = @JoinColumn(name = "ENTITY_FK", nullable = false))
  @OrderColumn(name = "ARRAY_INDEX", nullable = false)
  private List<EmbeddableData> data;

So I persist an instance of EntityA with 4 EmbeddableData instances in the data list which works as expected. Then I change one instance in the list keeping just 4 items and do a merge. However, instead of deleting the old item for the index I changed and then inserting the new item for that index, a new item is inserted which leaves 5 items in the database (2 with the same ARRAY_INDEX). Why is that the case?
