Hi Romain,
Please close this issue, the JBOSS team is looking at it under:

> CDI Producer Injection Point Divergence against WELD
> ----------------------------------------------------
>
> Key: TOMEE-1586
> URL: https://issues.apache.org/jira/browse/TOMEE-1586
> Project: TomEE
> Issue Type: Bug
> Affects Versions: 1.7.1
> Environment: Windows 7, Tomee 1.7.1
> Reporter: Nuno G. de M
> Priority: Minor
> Fix For: 1.7.2
>
>
> In a relative obscure/non-trivial Injection/production scenarion of CDI
> beans, there is a difference between the Injection Point passed to a producer
> under WELD bundled with Glassfish 3.1.2.X and Weblogic 12.1.2 vs TomEE
> open-cdi.
> Please see the zip file provided in the google drive link bellow.
> https://drive.google.com/file/d/0B_dEiNBGUsxqUkVXdWl3bmVXXzQ/view?usp=sharing
> The zip file cotains a .docx and builds on top of the sample project provided
> from TOMEE-1580 issue.
> Careful with the persistence.xml file of the project since its current commit
> state it will deploy glassfish 3.1.2 but not to TOmee 1_7_1 due to JNDI Name
> and Jar-file locaiton elements.
> In any case, the issue is describe in the docx.
> It is not clear if the bug is the implementation of WELD or of OpenCdi.
> In fact the behavior of OpenCDI seems to be more logical - from my point of
> view - but since the WELD is the reference implementation, you are being
> assigned this bug.
> TO summarize the issue:
> You will have a @RequestScoped bean being injected a @qualified "Holder bean".
> For this HolderBean there will be a producer.
> And the @Qualifier for the injection willl have an attribute value - e.g.
> @Qualifier(value="rockBalboa")
> (2) This producer that will provide the HolderInstance will use the
> BeanManager to create an instance of the "Holder" object tha tis specific fo
> the qualifier value (rockyBalboa)
> (3) When the BeanManager is creating the Holder object it will try to resolve
> the @Injection points of the holder.
> Namely there will be an
> @Iject
> @Qaulifier
> Instance<SomeInterface>
> Within this holder object.
> (4) The big diffence between WELD and OpenCDI now seems the be the following.
> Each of the Instances that will be iterated over this Instace attribute are
> created through a second producer.
> And on this second producer the InjectionPoint object is different in WELD
> and OpenCdi.
> In Weld the injection point has the same charateristics of the Ibjection
> point passed to the Producer of the Holder object.
> On OpenCDI the injection point has the characterists of the Holder object
> iself.
> When your code is based on WELD, this has the negative effect that if your
> code depended on the InjectionPoint in this very specific circunstance to
> carry the "rockyBalboa" value that existed in the @RequestScoped bean that
> initially asked for a Holder instance .... well only on Weblogic and
> Glassfish will this happen.
> On Tomee the producer for the Holder will get it, but not the producer for
> the nested beans.
> I would request that if this issue belongs to WELD that you forward the bug
> to them.
> I give low priority to this Bug - since there are programtic ways to make the
> code work under both implementations. The holder object has knowledge of the
> original injection point annotation and can therefore force its knowledge of
> "rockyBalboa" into the underlying beans ....
> But still, code has to be reworked to funciton under both implementations.
> Kindest regards,
> Nuno.
