> Special measures need to be taken for load-time-weaving with aspects, but using them without load-time weaving works normally OOB. However, if this kind of Spring configuration is used:
>     <!-- Test to get a data source -->
>     <jee:jndi-lookup id="dataSource" jndi-name="jboss/datasources/ExampleDS"/>
>     <!-- AOP part -->
>     <bean id="methodTraceAspect" class="fi.eis.applications.jboss.poc.gemini.spring.aop.support.api.MyMethodTraceAspect"/>
>     <aop:aspectj-autoproxy />
>     <!-- end AOP -->
>     <bean class="fi.eis.applications.controllers.HomeController">
>         <constructor-arg ref="dataSource" />
>     </bean>
> JBoss tries to use methodTraceAspect also on the data source. Data source is loaded by ModuleClassLoader that in has only visibility to org.jboss.jca.adapters* classes (confirmed with a debugger), so it cannot find the aspect class anymore, making aspect-j throw org.aspectj.weaver.reflect.ReflectionWorld$ReflectionWorldException: warning can't determine implemented interfaces of missing type
> fi.eis.applications.jboss.poc.gemini.spring.aop.support.api.MyMethodTraceAspect [Xlint:cantFindType].
> This has large problems in bigger applications, where general AOP pointcuts are used - no jboss-module stuff can be used as beans, anywhere. I'm aware of no workaround for this.
