AspectJWeaver's own logger?

[pierdeux]

What I hope is a trivial query:

I use the @Configurable annotation with certain domain objects and, therefore, start the JVM with the AspectJ Weaver:

java -javaagent:%path%/lib/aspectjweaver.jar

And I keep getting the following warning from log4j:

log4j:WARN No appenders could be found for logger (AspectJ Weaver).
log4j:WARN Please initialize the log4j system properly.

Yet my log4j.properties file does register the following loggers (among others):

log4j.logger.org.aspectj=debug, stdout, file
log4j.logger.org.springframework=info, stdout, file

So what is the root class which I need to register as logger in order to log AspectJ's work?
