Error getting @reference entity with Morphia

I have the Exec entity:

@Entity("Exec")
public class Exec {
  @Id
  private ObjectId id;
  private long initDate;
  private long endDate;
  public enum statuses {
    SUCCESS, FAIL, PARTIAL
  }
  private statuses status;
  @Reference(idOnly = true, ignoreMissing = true, lazy = false)
  Analysis analysis;
  @Reference(idOnly = true, ignoreMissing = true, lazy = true)
  Set<Conclusion> conclusions = new HashSet<Conclusion>();
  // getters and setters

which has a reference to the Conclusion entity:

@Entity("Conclusion")
public class Conclusion {
  @Id
  private ObjectId id;
  private Map<String, Object> params = new HashMap<String, Object>();
  private long initDate;
  private long endDate;
  public enum statuses {
    SUCCESS, 
    FAILURE
  }
  private statuses status; 
  private String errorMessage;
  private String stackTrace;
  Set<Map<String, Object>> data = new HashSet<Map<String, Object>>();

In the debugger, if I try to get the conclusions

Set<Conclusions> conclusions = mongoWrapper.getDataStore().createQuery(Exec.class).asList().get(0).getConclusions()

I get the following message:

com.sun.jdi.InvocationException occurred invoking method.

If I try to access the object, for example, doing the following:

conclusions.toArray()

it throws a RuntimeException, examining the stack trace:

org.mongodb.morphia.mapping.MappingException: Embedded element isn't a DBObject! How can it be that is a class java.lang.String

I tried changing a bunch of stuff, nothing really worked. Any ideas of what is the matter of the problem?

using concrete AnalysisConclusion in a set of Conclusion. remember that annotation are not inherited, then mark AnalysisConclusion with @Entity
