Provide ArC version of javax.enterprise.inject.spi.Unmanaged

[mkouba]

ArC does not fully support some parts of the CDI SPI such as AnnotatedType, InjectionTarget. However, we should be able to inject unmanaged instances. We should provide an ArC version of Unmanaged.

@mkouba is there any progress?
I would really like to get a something like in DS: https://github.com/apache/deltaspike/blob/master/deltaspike/core/api/src/main/java/org/apache/deltaspike/core/api/provider/BeanProvider.java#L460

[mkouba]

Hi @tandraschko, no progress yet. Anyway, the BeanProvider#injectFields() method is not a good example. First of all the name is misleading because it also invokes initializer methods. Furthermore, if a @Dependent bean instance is injected it is never destroyed correctly. This is fine unless the @Dependent bean declares a @PreDestroy callback. Finally, the InjectionTarget is primarily designed to create and destroy instances of the bean, to perform dependency injection and lifecycle callbacks and not only to inject an existing instance.

@mkouba yep, i understand
i generell i can't use Unmanaged in this case as JSF artifacts provides wrapping via constructors.

What could be a good alternative?
Loop all methods and manually invoke PostConstruct/PreDestory and also loop a fields for Injection points and try to get them via CDI.current()?

@mkouba can I help on this one. I want to discover arc and it seems a good way to take one ticket on it. I have start to implement interface but it is hard to understand use case, So I think I will add a test to check how it expect to work.

[mkouba]

Hi @dufoli, that would be great! However, I don't think this is a good "first issue" ;-). @manovotn @Ladicek guys do you remember a good ArC-related starter issue?

[manovotn]

Hmm, the list can be filtered on GH like this: https://github.com/quarkusio/quarkus/issues?page=1&q=is%3Aissue+is%3Aopen+label%3A%22area%2Farc%22

An easier one is perhaps this one with inheritance rules -. #41
But that's a lot of spec-checking, test writing etc to even get an idea about what should and shouldn't work...

You can pick whichever you like though, it mainly depends on how brave you are :-D

After discussion with @mkouba and @Ladicek, we have decided to not implement this feature. Details can be seen in the comments of this PR.
