No state snapshot is available on @Embedded class when using runtime enhancement via spring-tomcat-weaver

----------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-659
                 URL: https://issues.apache.org/jira/browse/OPENJPA-659
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 1.1.0
         Environment: Tomcat6, Java6, Mac OS X, Spring 2.5
            Reporter: Marc Logemann


i am getting this exception:

org.springframework.orm.jpa.JpaSystemException: No state snapshot is available for instance
of type "de.logentis.bwh.model.Payment", but this instance uses state-comparison for dirty
detection.; nested exception is <openjpa-1.1.0-r422266:657916 fatal general error> org.apache.openjpa.persistence.PersistenceException...

Here are the relevant pieces of the casses:

@Entity
@Table(name = "orders")
@VersionColumn(name = "_version")
public class Order {
...
   @Embedded
   Payment payment;
}

@Embeddable
public class Payment {

   @Basic
   @Enumerated(EnumType.STRING)
   @Column(name = "paymenttype")
   PaymentType type;

   @Column(name = "currency")
   String currency;

   @Column(name = "pricing")
   String pricing;

   @Column(name = "cost")
   int cost;
}

The point is, persisting is no problem at all, the exception will be thrown by issueing:

Query query = getEntityManager().createQuery("select o FROM Order o");
query.getResultList();
