This is basically a JSR-330 compliant variant of Spring's good old
ObjectFactoryCreatingFactoryBean. It can be used for traditional
external dependency injection configuration that targets a property or
constructor argument of type
javax.inject.Provider, as an

The target does not have to be a non-singleton bean, but realistically always will be (because if the target bean were a singleton, then said singleton bean could simply be injected straight into the dependent object, thus obviating the need for the extra level of indirection afforded by this factory approach).
