[weld-dev] potential weld jira

Thank you Martin!
I interpreted this enablement differently.
The CDI 1.2 spec states:
A bean is said to be enabled if:
it is deployed in a bean archive, and
it is not a producer method or field of a disabled bean, and
it is not specialized by any other enabled bean, as defined in
Specialization, and either
it is not an alternative, or it is a selected alternative of at least one
bean archive or the application.
Otherwise, the bean is said to be disabled.
In the above app, there are two jars. The jar beans-xml-modified2.jar.jar
does not enable the alternative and in its injection, it should only see
the CounterProducerModified. While in another jar, the alternative
AlternativeCounterProducerModified completely disabled the
CounterProducerModified. Any injection in that jar should only see the
specialized bean.
>From what you explained, the beans.xml in one jar enabled the alternative
bean and affect other jars. From my understanding, the enablement of
alternatives/interceptors are specific for that archive and should not
affect other jars.
Also OpenWebBeans behaves differently from Weld, and OpenWebBeans does
what I have expected (enablement are per jar only).
Many thanks,
Emily

Well, it seems the problem is that CounterProducerModified is
specialized by AlternativeCounterProducerModified and so it's not
enabled and therefore it's producer method is also disabled (see also
5.1.2. Enabled and disabled beans [1]), i.e. it's not available for
injection in beans-xml-modified2.jar. And
AlternativeCounterProducerModified is an alternative which is not
selected for beans-xml-modified2.jar.
It should work if you enable AlternativeCounterProducerModified globally
or select AlternativeCounterProducerModified for beans-xml-modified2.jar.
