When injecting parameterized types weld gives an error on start up. The code below fails with

	at org.jboss.weld.bean.AbstractProducerBean.checkProducerReturnType(AbstractProducerBean.java:180)


   @Inject
   @Parameterized
   Parameterized1<Parameterized2<Double>> parameterized;

...

   @Produces
   @Parameterized

   {
      return new Parameterized1();
   }
