InvalidStateException deleting an instance with a timestamp in its primary key
------------------------------------------------------------------------------

                 Key: OPENJPA-2072
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2072
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 1.2.2, 1.2.1, 1.2.3
         Environment: Linux, JUnit + Spring and HSQLDB in a case; Windows, WebSphere and DB2
in another case
            Reporter: Ernesto Ricci


Attempting to remove an instance that has a timestamp field in its primary key results 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);
 }

Here is the error I get:
...

N.B.: the error doesn't happen if the primary key annotation (@Id) is moved on the other field
of the entity, which is not a timestamp but a char:
 @Column(name="T")
 private Timestamp idTsp;

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