4.8. Summary

In this chapter, we explored several advanced OSGi bundle and service features that allow you to develop flexible, extensible, and robust OSGi applications.

The OSGi framework provides several options for minimizing bundle dependencies. You can restrict a resource to be within a private package and thus not visible to any other bundle. You can also choose to export only a subset of the classes residing in a package, thus reducing the number of classes that make up the exported package contract. Finally, you learned that you should avoid creating bundle dependencies using the Bundle-Required header, because it can cause split packages and cause other problems.
