Using FetchType.EAGER on OneToMany using jta data source causes result set is closed (DB2)
------------------------------------------------------------------------------------------

                 Key: OPENJPA-260
                 URL: https://issues.apache.org/jira/browse/OPENJPA-260
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 0.9.7
         Environment: WebSphere Platform 6.1 [BASE 6.1.0.7 cf70711.17] [WEBSERVICES 6.1.0.7

When adding "fetch=FetchType.EAGER" to a entity, I get a org.apache.openjpa.persistence.PersistenceException:
[ibm][db2][jcc][10120][10898] Invalid operation: result set is closed. exception. This is
on a persistence unit that is configured to use JTA Data Source (see config below) (running
on WebSphere 6.1.0.7 with DB2 XA Driver). This works when using RESOURCE_LOCAL transaction-type
(direct to DB2). The code also works if I remove the "fetch=FetchType.EAGER", therefore I
presume there is a bug with the handling of managed transactions with EAGER fetching.

persistence.xml:
	<persistence-unit name="crs" transaction-type="JTA">
		<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
		<jta-data-source>java:comp/env/jdbc/crsDS</jta-data-source>
		
		<class>crs.bus.entity.Customer</class>
  		<class>crs.bus.entity.Address</class>
		<class>crs.bus.entity.CustomerAddress</class>
				
		<properties>
 			<property name="openjpa.TransactionMode" value="managed" />
			<property name="openjpa.ConnectionFactoryMode" value="managed" />
			<property name="openjpa.jdbc.DBDictionary" value="db2" />
		</properties>

Entity:
@Entity
@Table(name="Customer", uniqueConstraints={@UniqueConstraint(columnNames="id")})
public class Customer implements Serializable  {
	/** .*/
	private static final long serialVersionUID = 4011736633726247664L;
	@Id
	@GeneratedValue(strategy=GenerationType.IDENTITY)
	private long id;
	@Basic
	private String name;
	@OneToMany(cascade={CascadeType.ALL}, fetch=FetchType.EAGER)
	private List<CustomerAddress> addresses;
    @Basic
    private Date created = new Date();	
....
}
