Since Java SE forms the backbone to many products across several industries—and OSGi in many ways influences and modifies the underlying operation of the JVM—incorporating OSGi into Java SE is not as simple as incorporating a niche JSR. Like most processes involving technology standards, a standard making its way into a product will depend heavily not just on being a best-of-breed technology, but also on a mix of business interests, corporate politics, and when the user community acknowledges its pressing need.

A service might be the only thing being updated, but if other bundles have type dependencies on this same updated bundle, OSGi ensures changes are propagated to all dependent bundles by uninstalling and reinstalling each one. This is not the case with services, since services are always consulted via OSGi’s registry. If a bundle only contains services and is updated, there is no need to propagate updates to bundles using this service; the OSGi registry will ensure all consuming bundles obtain a reference to the updated service the next time it is accessed.

You may find a few Java classes depend on the use of some third-party API, others on an external resource like a database connection, and yet others on an inheritance hierarchy imposed by some other classes. So you could effectively say dependencies are everywhere, but while these dependencies in themselves are necessary to achieve the ultimate goal of a functioning application, the way you go about defining them can have broad implications in the overall design of an application.
