Hi, is option 3 also correct? Since the explanation says: "3. It does not need to export its packages to the outside world. The user of the service is not even aware of the actual implementation class or the module that provides the implementation of the service. There is no restriction on exporting the packages though."

Option 3 is invalid because it does not specify the provides clause correctly. The "with" part is missing.
provides org.broker.api.Installer with com.foo.AppInstaller;
