It's too late to add to this list here - the (other) `MBeanExporter` may have already been instantiated by now and it registers its MBeans in `afterPropertiesSet()`. That's why it's a `BFPP`.

I guess the issue you are trying to resolve is that the annotation BPP is adding more beans.

Perhaps you can build the `excludedBeans` in `afterPropertiesSet()` here instead?
