This annotation is placed on an injection point that is to be injected with the ActiveDescriptor that was used to create the instance.

The following things must be true of injection points annotated with Self

• The injection point must have the type ActiveDescriptor. The generic type is ignored
• The injection point must have no qualifiers
• The injection point must not be annotated org.jvnet.hk2.annotations.Optional
• The class must not be getting injected with the ServiceLocator#inject(Object) method

Furthermore, the ActiveDescriptor that can be injected have the following restrictions:

• The ActiveDescriptor was not pre-reified prior to being bound (i.e. third-party ActiveDescriptors)
• The ActiveDescriptor is not a DescriptorType#PROVIDE_METHOD

A valid injection point that is annotated with Self will not go through the normal resolution process, and hence cannot be customized.
