I have a plugin which is currently resolving Spring Bean references, and I like the interface the Spring plugin has for accessing Spring Bean data.  One thing I have yet to find is a way to quickly identify the target bean for a proxy.  For example, I have a number of beans which are proxied with ProxyFactoryBean and I would like the target beans to be removed from a list of available variants.  How could I find the target beans, and remove it from my list without having to roll my own implementation to do this?
