Spring Boot 1.4.0にアップグレードした後、AbstractPlatformTransactionManagerのNullPointerException

Spring Boot 1.3.2から1.4.0にアップグレードしましたが、アプリケーションを起動できません-BeanPostProcessorサードパーティのオープンソースLazy Chopperを呼び出します。これを実行しようとするとgetTransaction()、ここで失敗します。

public abstract class AbstractPlatformTransactionManager implements PlatformTransactionManager, Serializable {

    protected transient Log logger = LogFactory.getLog(getClass());
    // ...
    @Override
    public final TransactionStatus getTransaction(TransactionDefinition definition) throws TransactionException {
        Object transaction = doGetTransaction();

        // Cache debug flag to avoid repeated checks.
        boolean debugEnabled = logger.isDebugEnabled(); // logger is null here

ブレークポイントをそこに配置すると、logger確かにそうなることがわかりますがnull、言及する価値がある場合は、その場でLogFactory.getLog(getClass())自分自身を呼び出すと、適切なロガーが得られます。

正しいロガーが初期化される前に、どういうわけか私のBeanがそのメソッドを呼び出しているように見えますか？..

これが私が得た完全なスタックトレースです：

デフォルトのlogback自動構成を使用しており、微調整は行っていません。

更新＃1：そのメソッドの周りに定義されたポイントカットがあります。

            <aop:pointcut id="transactionManagerPointcut"
                      expression="(execution(* org.springframework.transaction.PlatformTransactionManager.getTransaction(..)))"/>

更新＃2：それで、その側面を取り除くことがトリックをしたようです..それでも、これを克服する理由と方法を理解しようとしています。

アスペクトの定義は次のとおりです。

            <aop:pointcut id="transactionManagerPointcut"
                      expression="(execution(* org.springframework.transaction.PlatformTransactionManager.getTransaction(..)))"/>

        <aop:pointcut id="allServices"
                      expression="(execution(* com.decision..tx..*.*(..))) or (execution(* com.sapiens.bdms..tx..*.*(..))) &amp;&amp; !@annotation(com.sapiens.bdms.core.persistence.annotation.NotTransactional)"/>
        <aop:aspect ref="sessionFilterConfigurator">
            <aop:before method="setupFilter"
                        pointcut-ref="allServices"/>
            <aop:after-returning method="setupFilter"
                                 pointcut-ref="transactionManagerPointcut"/>
        </aop:aspect>

そして、これがアスペクトメソッドです：

    @Component("sessionFilterConfigurator")
public class SessionFilterConfigurator {
    @Resource
    private Collection<FilterConfiguration> filterConfigurations;
    @Resource
    private SessionFactory sessionFactory;
    @Resource
    private FiltersDisconnector filtersDisconnector;

    public void setupFilter() throws Throwable {
        Session session = sessionFactory.getCurrentSession();
        if (AutoEnableConfig.isFiltersEnabled()) {
            for (FilterConfiguration filterConfiguration : filterConfigurations) {
                Filter filter = session.enableFilter(filterConfiguration.getFilterName());
                for (Map.Entry<String, Object> entry : filterConfiguration.getFilterParameters().entrySet()) {
                    filter.setParameter(entry.getKey(), entry.getValue());
                }
            }
            AutoEnableConfig.disableFilterEnabling();
            ((EventSource) session).getActionQueue().registerProcess(filtersDisconnector);
        }
    }
}

この場合、なぜそれがロガーを壊すのか、そしてなぜ1.4.0にアップグレードした後でのみなのかについてはまだ明確ではありません...
