The title should have been "Everything that is wrong with Spring ... ". Then it would not have been especially accurate, but more accurate. I like Java better than I like Spring. Spring made a framework out of an idea, but not all ideas should be packaged. Ideas can also be embraced. Dependency injection is an idea that should be embraced, but not as a packaged solution. It is a pattern, not a a software project.
Actually, it would then have been entitled "A class that extends the Spring AOP easily and unobtrusively", or probably just as accurately "everything that is right with Spring".
I seriously don't think you understand that at the core of Spring is an IoC container - it just so happens that Spring does a lot of other useful things.
