NPE with DebugInterceptor

[res1st]

Hi,
i added a debugInterceptor to my SWS project this way:

<aop:config proxy-target-class="true">
    <aop:advisor advice-ref="debugInterceptor" pointcut="execution (public * de.test.webservice..*(..))" />
</aop:config>
<bean id="debugInterceptor" class="org.springframework.aop.interceptor.DebugInterceptor"/>

My JAXB generated classes are below the webservice package(de.test.jaxb...)
But if i call my webservice, i get this npe:

806167 [http-8080-Processor24] [...]

PS.: I use Spring 2 RC2, SWS nightly 20060727

Now that's weird. The only thing happening on line 43 is a method call on the unmarshaller and a method call on incoming request message. The request message can't be null, because you validate it, so it must be the unmarshaller. But that can't be null either, because its presence is checked in the afterPropertiesSet().

Can you perhaps debug your app, and see what the problem is?

Thanks,

I think i can't debug it because there are no source code packages available for the nightly builds.
