Mentioned in #722. So, one of these PRs should be rebased and polished after merging another.
And also, Soby, please:
* update Copyright to 2013 in all touch classes
* add your name to authors list
* clean-up unused imports
* keep imports in order: static, java, apache, etc., spring
* try always add import. I'm about `org.springframework.util.ClassUtils.isCglibProxyClass` below

Thanks
