> CDI-268 introduces a set of factories to deal with the chicken-egg problem when creating Beans and Producers/InjectionTargets.
> Unlike InjectionTargetFactory, the ProducerFactory interface does not address the problem properly.
> In order to create a Producer implementation for a producer field/method, the following ingredients are needed:
> * an AnnotatedField / AnnotatedMethod
> * a declaring bean (bean for the class the producer field/method is declared on - the field/method is invoked on instances of the declaring bean) . Declaring bean does not need to be specified if the field/method is static
> * bean for which the producer is created - this is needed in order for Producer.getInjectionPoints.getBean() to return the right thing. The bean is optional an may not be specified if the Producer is created for a non-contextual object
> The following (slightly modified) SPI should handle all the requirements:
> {noformat}
> public interface ProducerFactory<X> {
>     public <T> Producer<T> createProducer(Bean<T> bean);
> }
> {noformat}
> {noformat}
> public interface BeanManager {
>     public <X> ProducerFactory<X> getProducerFactory(AnnotatedField<? super X> field, Bean<X> declaringBean);
>     public <X> ProducerFactory<X> getProducerFactory(AnnotatedMethod<? super X> method, Bean<X> declaringBean);
>     public <T, X> Bean<T> createBean(BeanAttributes<T> attributes, Class<X> beanClass, ProducerFactory<X> producerFactory);
> }
> {noformat}
> Notice the additional *declaringBean* parameter for getProducerFactory() and modified type parameters in createBean() and ProducerFactory.
