Java 在单独的类加载器中隔离模块后发生Spring IllegaAccess异常

我有一个问题涉及

我们通过创建一个bean来解决这个问题，该bean使用Spring定义的类加载器bean作为属性注入，从未存储在官方

WEB-INF/lib

文件夹中的类调用服务

下面是bean的定义

<bean id="metainfJarClassloader" class="com.jdotsoft.jarloader.JarClassLoaderFactory" factory-method="create"/>
<bean id="jadesFactory" class="it.csttech.proxy.jades.JadesFactory">
      <constructor-arg index="0" ref="metainfJarClassloader"/>       
</bean>
<bean id="bouncyCastleBeanFactory" class="it.csttech.proxy.bouncyCastle.BouncyCastleBeanFactory">
      <constructor-arg index="0" ref="metainfJarClassloader"/>       
</bean>


    <bean id="timestampService" class="it.csttech.pcp.services.spring.TimestampServiceImpl" lazy-init="true">
        <property name="timestampServerConfig">
            <bean factory-bean="jadesFactory" factory-method="createTSServerCfg">
            -------------------
            </bean>
        </property>
        <property name="jadesFactory" ref="jadesFactory" />
        <property name="bouncyCastleBeanFactory" ref="bouncyCastleBeanFactory" />
        <property name="jarClassLoader" ref="metainfJarClassloader" />
    </bean>

TimestampServiceImpl将从META-INF目录加载其依赖类

我不明白的是，为什么在启用该组件并仅由延迟初始化的认证时间戳服务调用之后，我会在Spring中得到大量的

IllegalAccessError

s

具体来说，我无法再访问MVC控制器中定义的任何

私有静态类

证据：
