I'm afraid there isn't such a tutorial or description, but it should work.
If you declare
in your application context, the kernel should automatically replace Spring's standard LoadTimeWeaver with a KernelLoadTimeWeaver implementation that's OSGi-aware.
Spring's AspectJ-based load time weaving support should then just work as expected.
Please could you try that and let us know if you hit a problem. If you are successful and fancy providing a little tutorial or description, or at least posting your findings here, that would be a nice contribution to the project.
