Implementation of AspectJ's IMessageHandler interface that routes AspectJ weaving messages through the same logging system as the regular Spring messages.

Pass the option...

-XmessageHandlerClass:org.springframework.aop.aspectj.AspectJWeaverMessageHandler

to the weaver; for example, specifying the following in a "META-INF/aop.xml file:

<weaver options="..."/>
