Comment résoudre org.mise en veille prolongée.StaleObjectStateException lors de la copie des données à partir d'une base de données à un autre?

Je suis en train de copier des données d'une base vers une autre. Tout fonctionne bien, jusqu'à ce que l'une des lignes dans la base de données source est modifié (trace de la pile ci-dessous) . L'ajout de nouvelles lignes à destination de la base de données fonctionne comme prévu.

J'ai un fichier de contexte pour chaque connexion de base de données (mysql et hsqldb), comprenant les haricots:

    <bean id="mysqlDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${mysql.driver}" />
        <property name="url" value="${mysql.url}" />
        <property name="username" value="${mysql.username}" />
        <property name="password" value="${mysql.password}" />
    </bean>

    <bean id="mysqlTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="mysqlEntityManagerFactory" />
        <property name="dataSource" ref="mysqlDataSource" />
    </bean>

    <bean id="mysqlEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource"          ref="mysqlDataSource" />
        <property name="jpaVendorAdapter"    ref="mysqlVendorAdaptor" />
        <property name="packagesToScan"      value="my.packages.to.scan"/>
    </bean>

    <bean id="mysqlEntityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
        <property name="entityManagerFactory" ref="mysqlEntityManagerFactory"/>
    </bean>

    <bean id="mysqlVendorAdaptor" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" >
        <property name="showSql" value="true" />
        <property name="generateDdl" value="true" />
        <property name="databasePlatform" value="${mysql.dialect}" />
    </bean>

Dans mon @Service - je créer un JpaRepository pour chaque connexion de base de données:

@Autowired
private EntityManager hsqldbEntityManager;

@Autowired
private EntityManager mysqlEntityManager;

private MyRepository hsqldbDao;
private MyRepository mysqlDao;

public void init() {
    hsqldbDao = new JpaRepositoryFactory(hsqldbEntityManager).getRepository(MyRepository.class);
    mysqlDao = new JpaRepositoryFactory(mysqlEntityManager).getRepository(MyRepository.class);
}

MyRepository est très simple:

public interface MyRepository extends JpaRepository<MyClass, byte[]>{ }

Je suis câblage 2 méthodes de service ensemble à l'aide de Spring Integration. Le service méthodes sont les suivantes:

@Transactional("mysqlTransactionManager")
public List<MyClass> findAll() {
    List<MyClass> list= mysqlDao.findAll();
    return list;
}

@Transactional("hsqldbTransactionManager")
public void persist(List<MyClass> list) {
    hsqldbDao.save(list);
    hsqldbDao.flush();
}

J'ai essayé de détacher la liste des deux EntityManagers et profonde clonage de la liste avant de l'enregistrer, avec le même message d'erreur. Donc je pense qu'il a quelque chose à voir avec la façon dont j'ai configuré les transactions/entitymanagers.

Toute aide appréciée.
