Hibernate configuration with cglib

[croudet]

I try to set the Hibernate property 'hibernate.cglib.use_reflection_optimizer' to false:

<bean id="HibernateSessionFactory" 
 class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
  <property name="mappingResources">
     <list>
        <!-- This will include a list of all the mapping files 	to be used for this configuration. --> 
         &fileList; 
      </list>
   </property>
   <property name="hibernateProperties">
     <props>
        ....
        <prop key="hibernate.dialect">$&#123;hibernate.dialect&#125;</prop>
        <prop key="hibernate.cglib.use_reflection_optimizer">false</prop>
     </props>
   </property>
   <property name="dataSource">
       <ref local="DBDataSource"/>
   </property>
</bean>

but what ever the value of this property, Hibernate still uses cglib:

2004-09-28 19:54:59,642 [main] INFO  net.sf.hibernate.cfg.Environment - Hibernate 2.1.6
2004-09-28 19:54:59,642 [main] INFO  net.sf.hibernate.cfg.Environment - hibernate.properties not found
2004-09-28 19:54:59,642 [main] INFO  net.sf.hibernate.cfg.Environment - using CGLIB reflection optimizer

Does anyone knows how to disable the cglib optimizer?

[irbouho]

hibernate.cglib.use_reflection_optimizer is a system level property.

System-level properties are shared by all factory instances and are always determined by the Environment properties.
The only system-level properties are
hibernate.jdbc.use_streams_for_binary
hibernate.cglib.use_reflection_optimizer
Environment properties are populated by calling System.getProperties() and then from a resource named /hibernate.properties if it exists. System properties override properties specified in hibernate.properties.

I tried both ways to disabled cglib in hibernate:

I used the VM parameter:

-Dhibernate.bytecode.use_reflection_optimizer=false 
-Dhibernate.cglib.use_reflection_optimizer=false

I also created a hibernate.properties file in my classpath:

hibernate.bytecode.use_reflection_optimizer=false
hibernate.cglib.use_reflection_optimizer=false

Hibernate still uses cglib if i activate Spring AOP transaction handling in my application. Without AOP transaction handling cglib is not used.

Can i disable usage of cglib in hibernate when i use Spring AOP transaction handling?

I found a solution here:

This error may be produced because hibernate is trying to set null to a property that is a primitive. Just change the property type to its wrapper (e.g. int -> Integer)
