-/**
- * OSGi annotation processing
- * OSGi bundles are not introspected by OSGiImplementation when a component is created.
- * Instead if the list of implementation classes is specified in <implementation.osgi/>,
- * the classes are introspected when the bundle is resolved. The classes are loaded using
- * the bundle classloader, and hence the delay in annotation processing is inevitable.
- * There is one other difference compared to implementation.java. While instances (and
- * the instance class) are associated with a component in Java, all Java annotations from
- * the component implementation class apply to all the component instances. In OSGi,
- * instances are associated with services, and a bundle can register multiple services.
- * Hence annotations from classes need to be stored separately so that the right ones
- * can be associated with the service instance.
