in this error:
> org.apache.openjpa.persistence.InvalidStateException: Operation attempted on a deleted
instance.
> Suppose I have this table:
> CREATE TABLE test_tsp (
>    t Timestamp,
>    desc char(30)
> )
> containing just the following row:
> INSERT INTO test_tsp(T,DESC) VALUES ( CURRENT_TIMESTAMP, 'one')
> the table is mapped to this JPA Entity
> @Entity
> @Table(name="TEST_TSP")
> public class TestTsp implements Serializable {
>  private static final long serialVersionUID = -5756434331459759089L;
>  @Column(name="T")
>  @Id
>  private Timestamp idTsp;
>  @Column(name="DESC")
>  private String desc;
>  public TestTsp() {
>   super();
>  }
> ...getters and setters here...
> }
> and the following code attempts a delete of the row I've inserted
>  Query query = em.createQuery("select t from TestTsp t where t.desc='one'");
>  List<TestTsp> list = query.getResultList();
>  for (TestTsp t : list) {
>   em.remove(t);

field of the entity, which is not a timestamp but a char:

>  private Timestamp idTsp;
>  @Column(name="DESC")
>  @Id
>  private String desc;
