Estou tentando criar um protótipo de um código Hibernate bastante simples originário de um tutorial e estou recebendo um erro que não entendo profundamente no cglib2 (o rastreamento completo da pilha está no final deste post). Provavelmente, estou tentando criar 'productBoProxy' de acordo com meu simplesa Principal( e XML do bean (abaixo).

Eu tentei muitas versões diferentes do cglib sem sucesso. Sou muito grato a qualquer pessoa que possa me ajudar a encontrar o caminho certo para resolver isso.

App.java:

ApplicationContext appContext
    = new ClassPathXmlApplicationContext( "resources/config/BeanLocations.xml" );
...
productBo = ( ProductBo ) appContext.getBean( "productBoProxy" );
productBo.save( product, 100 );

Product.xml:

...
<!-- This is a proxy factory bean; see App.java -->
<bean id="productBoProxy"
      class="org.springframework.aop.framework.ProxyFactoryBean">
  <property name="target" ref="productBo" />
  <property name="interceptorNames">
    <list>
      <value>transactionInterceptor</value>
    </list>
  </property>
</bean>
...
