[appengine-java] jdo and pm.close()?

[Andrés Cerezo]

If i want to execute this source code without errors, I have to delete the
first pm.close(); Anyone knows why?


          final Date date = new Date();
EmployeeData employee = new  EmployeeData("John", "Doe", date);

          PersistenceManager pm = PMF.get().getPersistenceManager();

          final Long id = pm.makePersistent(employee).getId();

          // From a different persistence manager, look up the // object

          employee = pm.getObjectById(EmployeeData.class, id);
          assertEquals(employee.getFirstName(), "John");
          assertEquals(employee.getLastName(), "Doe");

          pm.close();

         pm = PMF.get().getPersistenceManager(); */


          EmployeeData employee2 = new EmployeeData("John2", "Doe2", date);

          final Long id2 = pm.makePersistent(employee2).getId();

          // From a different persistence manager, look up the // object

          employee2 = pm.getObjectById(EmployeeData.class, id2);
          assertEquals(employee2.getFirstName(), "John");
          assertEquals(employee2.getLastName(), "Doe");

          pm.close();

Thanks.
