IllegalAccessError when ContextLoader creates sessionFactory

[goodav]

I get an IllegalAccessError from the cglib libraries when the ContextLoader attempts to initialize the sessionFactory bean defined in my applicationContext.xml file. I've tried different version of the cglib-xxx.jar with no success. Does anyone have any ideas as to what I could be configuring/doing wrong? Is this an appropriate area in the forum for this post?

Here is relevant portion of applicationContext.xml:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  		<property name="driverClassName">
  			<value>com.mysql.jdbc.Driver</value>
		</property>
		<property name="url">
		    <value>jdbc&#58;mysql&#58;//localhost&#58;3306/DEV</value>
		</property>
		<property name="username">
		    <value>developer</value>
		</property>
		<property name="password">
		    <value>developer</value>
		</property>
	</bean>
	<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource"/>
		</property>
		<property name="mappingResources">
			<list>
			<value>com/dev/domain/hibernate/User.hbm.xml</value>
			<value>com/dev/domain/hibernate/UserInfo.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">net.sf.hibernate.dialect.MySQLDialect</prop>
				<!--<prop key="hibernate.cglib.use_reflection_optimizer">false</prop>-->
			</props>
		</property>
	</bean>

Here is exception:

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed

I think you first need to clarify whether this issue involves Spring or is purely a Hibernate issue. Can you read the config with Hibernate, without Spring, to isolate the Hibernate and Spring config?

I ended up solving the problem by using cglib-full-2.0.jar, so it is not a spring issue. Thanks for the advice.
