ошибка во время операции MassIndexer: отключенный объект передан для сохранения, HSEARCH000058: HSEARCH000116

У меня проблема во время работы massindexer.

Я использую JPA 2.0-cr-1, Hibernate search 4.2.0.Final с hibernate 4.1.9.Final и lucene версии 3.6.2. Я также использую пружинный каркас.

Похоже, у меня возникли проблемы, так как я использую поиск Hibernate 4.2.0.Final вместо поиска Hibernate 3.3.0.Final.

Я проиндексировал объект User.java:

@Entity
@Table(name = "user", uniqueConstraints = {
    @UniqueConstraint(columnNames = "email"),
    @UniqueConstraint(columnNames = "login") })
@Indexed
@FullTextFilterDefs({
@FullTextFilterDef(name = "userFilterGroup", impl = UserFilterGroupFactory.class   ,cache=FilterCacheModeType.NONE),
@FullTextFilterDef(name = "userFilterAccountType", impl = LuceneStrFilterFactory.class ,cache=FilterCacheModeType.NONE)})
public class User extends TemporalBehavior implements java.io.Serializable {

/**
 * 
 */
private static final long serialVersionUID = -626437341655804022L;


public static final String[] SEARCH_FIELDS = new String[]{"id","login","email","profile.lastname","profile.firstname"};

private Integer id;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
@NotNull
@Size(min=1, max=255)
//@Size(min=6, max=255) //L'ancienne plateforme permet des login min=1
private String login;

@NotNull
@Size(min=1, max=255)
//@Size(min=6, max=255) //L'ancienne plateforme permet des pass min=1
private String password;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
@Email
private String email;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
private String partnerRef;

private Set<Contract> contracts = new HashSet<Contract>(0);
private Set<Contract> ownedContracts = new HashSet<Contract>();

    ....
    @ManyToMany(fetch = FetchType.LAZY, cascade=CascadeType.PERSIST)
@JoinTable(name = "user_contract", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "contract_id", nullable = false, updatable = false) })
public Set<Contract> getContracts() {
    return this.contracts;
}

    @OneToMany(mappedBy="owner")
public Set<Contract> getOwnedContracts() {
    return this.ownedContracts;
}

    ...

    }

Операцию Massindexer я назвал:

FullTextEntityManager fem = Search.getFullTextEntityManager(em);
    try {
        fem.createIndexer(User.class)
        .purgeAllOnStart(true)
        .optimizeAfterPurge( true )   
        .optimizeOnFinish( true )
        .batchSizeToLoadObjects(100)  
        .threadsForSubsequentFetching(8)  
        .threadsToLoadObjects(4)  
        .cacheMode(CacheMode.NORMAL)    // todo : It is recommended to leave cacheMode to CacheMode.IGNORE (the default), as in most reindexing situations the cache will be a useless additional overhead; 
        .startAndWait();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Дальше массиндексер делает свою работу, но есть ошибки (не для всех данных пользователя):
