CGLIB with spring throws IllegalAccessError
===

I have a spring app with aop enabled using cglib proxies for logging:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
    <aop:aspectj-autoproxy proxy-target-class="true"/>

    <bean id="loggingPointcuts" class="com.coverall.integration.commons.logging.LoggingPointcuts"/>

    <bean id="loggingAspect" class="com.coverall.integration.commons.logging.LoggingAspect"/>
    </beans>

I am using cglib-nodep-2.2.2.jar with spring 3.1.1
This works well in tomcat or jetty. However when I deployed this on OC4J (with jdk1.6) I get the following error:
The class its trying to proxy - ComponentRegistryImpl is package private
