Javelin(only the Spring part) will benefit the project in the long term. We switch Ant to
Maven in 4.0, how about we switch our home-made DI to Spring in 4.1? Maven & Spring both
popular/modern/fashion tool/framework in the Java world,  the more we use them in the project,
the more java developers we can attract  into this project?
It does take a lot of our effort to make the switch on the Javelin branch, even though from
feature point of view, we add nothing in Javelin branch.
