title: Spring ApplicationContext.getBean(Class c) not working for proxy classes
body: <p>I need to look up beans via their class type. When the beans have been wrapped by a Proxy (some methods are @Transactional) - the ApplicatoinContext fails to find them. I find that if I look them up via an interface, it works but in this case I'm working with a concrete class type. I know the bean is of the type I'm looking for but the getBean() method fails. </p>
  
  <p>I can debug (and fix) the problem in Spring's AbstractBeanFactory code. The issue is that it checks the type of the beanInstance against type I'm requesting but the beanInstance.getClass() is a Proxy. AbstractBeanFactory should compensate for this and compare the type to the proxy's target class. </p>
  
  <p>I have a fix for this but I don't particularly want to use a patched version of Spring and I suspect there must be something I can configure to get this working, or is this really a bug? </p>
