Given the vast number of Spring-based projects and the most recent up-surge in the desire to benefit from OSGi's dynamic modularity it has become clear that there is a understandable difficulty in moving projects of any complexity to OSGi from a pure Spring architecture. The issue is that there are some design changes that must be made in moving traditional java applications, including Spring based ones, to OSGi. OSGi has a puritanical solution to a vast number of problems caused by the traditional architectures, but in order to gain from those solutions a considerable amount of redesign has to be done.
