Changing our meeting time slot?
by Antoine Sabot-Durand
Hi all,
Following last week discussion, you’ll find a Doodle link below to choose your the best time slot for our meeting. I propose time slot on several days for 6-7pm CET or 8-9pm CET (I’m usually not available between 7-8pm). I took into consideration USA and Europe (majority of us) TZ.
Please fill the doodle so we could change our meeting slot and have more people able to join.

Re: [cdi-dev] [weld-dev] How to skip CDI injection if a property is not configured in batch application?
by Mark Struberg
There is an easy trick though which we do at BatchEE:
The producer is @Dependent. So you can simply inject the InjectionPoint and inspect the current value in case it is not yet set.

Re: [cdi-dev] [weld-dev] How to skip CDI injection if a property is not configured in batch application?

Not possible. The jobs can also only get added at runtime. So you don not have this information during bootstrap.

[JBoss JIRA] (CDI-516) Firing events with dynamic parameterized types

------------------------------------
Opting for the second solution, as application code should not have to deal with java.lang.reflect.* and framework code (that needs to handle generic types) should not have to mess around with convenience oriented Instance- or Event-related code.

[JBoss JIRA] (CDI-516) Firing events with dynamic parameterized types
by Antonin Stefanutti (JIRA)
[ https://issues.jboss.org/browse/CDI-516?page=com.atlassian.jira.plugin.sy... ]
Antonin Stefanutti updated CDI-516:
-----------------------------------
Description:
For the time being, either by using {{Event.select(...)}}, respectively {{BeanManager.fireEvent(...)}}, it is not possible to fire an event whose runtime type is a dynamic parameterized type, as specified in [The {{Event}} interface|http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#event]:
{quote}
If the container is unable to resolve the parameterized type of the event object, it uses the specified type to infer the parameterized type of the event types.
If the runtime type of the event object contains an unresolvable type variable, an {{IllegalArgumentException}} is thrown.
{quote}
Respectively in [Firing an event|http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#bm_fire_event]:
{quote}
If the runtime type of the event object contains a type variable, an {{IllegalArgumentException}} is thrown.
{quote}
While, it is possible to pass a {{TypeLiteral}} to the {{Event.select(...)}} method, e.g.:
{code}
@Inject
Event<Object> event;
event.select(new TypeLiteral<String>() {});
{code}
It is not possible to pass a type variable known at runtime as the {{TypeLiteral}} class relies on the declared type variable and does not permit to override that behavior as the {{TypeLiteral.getType()}} method is declared {{final}}.
Yet, there are use cases where that need is valid, for example:
{code}
<T> CdiEventEndpoint<T> cdiEventEndpoint(InjectionPoint ip, CamelContext context, @Any Event<Object> event) throws Exception {
// Represents the runtime type for T
Type type = ((ParameterizedType) ip.getType()).getActualTypeArguments()[0];
String uri = endpointUri(type, ip.getQualifiers());
if (context.hasEndpoint(uri) == null) {
// Work around to pass the dynamic type
TypeLiteral<T> literal = new TypeLiteral<T>() {};
for (Field field : TypeLiteral.class.getDeclaredFields()) {
if (field.getType().equals(Type.class)) {
field.setAccessible(true);
field.set(literal, type);
break;
}
}
// Here we used the dynamic type
Event<T> typedEvent = event.select(literal, ip.getQualifiers().toArray(new Annotation[ip.getQualifiers().size()]));
context.addEndpoint(uri, new CdiEventEndpoint<>(typedEvent, uri, context));
}
return CamelContextHelper.getMandatoryEndpoint(context, uri, CdiEventEndpoint.class);
}
{code}
In the example above, the {{TypeLiteral}} class could have a constructor taking the dynamic type as argument.
Another alternative would be to enrich the {{BeanManager}} SPI with the following method:
{code}
public void fireEvent(Object event, Type type, Annotation... qualifiers);
{code}
That use case is taken from the [CDI event Camel endpoint|https://github.com/astefanutti/camel-cdi/blob/84426570bcd7815eb9...] in the [Camel CDI extension|https://github.com/astefanutti/camel-cdi].

explicit bean archives discovery-mode 'annotated'
by Mark Struberg
Hi!
I think I’ve implemented the behavour the spec defines - but it does not make much sense.
First let’s look at the spec:
11.5.6. ProcessAnnotatedType event
The container must fire an event, before it processes a type, for every Java class, interface
(excluding the special kind of interface declaration annotation type) or enum DISCOVERED
as defined in Section 12.4.1, “Type discovery”
12.4.1 defines…
First the container must discover types. The container discovers:
• each Java class with a bean defining annotation in an implicit bean archive.
And in 2.5 we can read
"f the bean discovery mode is annotated then:
• bean classes that don’t have bean defining annotation (as defined in Section 2.5.1, “Bean defining annotations”) and are not bean classes of sessions beans, are NOT DISCOVERED“
Which to me means that for a BDA with discovery-mode = „annotated“ we ONLY must fire ProcessAnnotatedType for classes with bean defining annotations, and NOT for interfaces or enums.
If this is true, then it is a huge mess for lots of CDI Extensions. It basically renders the ‚annotated‘ mode pretty much useless.
What we really need instead is a mode which will not automatically make a @Dependent bean out of every class later. But I really would ‚discover‘ all classes in a BDA and pass them to ProcessAnnotatedType.
Some way to fix this or do we have to wait for CDI-2.0 to repair CDI-1.1?

[JBoss JIRA] (CDI-420) add a bean-discovery-mode 'detected'
by Jozef Hartinger (JIRA)
[ https://issues.jboss.org/browse/CDI-420?page=com.atlassian.jira.plugin.sy... ]
Jozef Hartinger commented on CDI-420:
-------------------------------------
This interface/enum discovery use-case very often uses a marker annotation (e.g. @MessageBundle). Such extension can work around this limitation by making the marker annotation a @Stereotype.
> add a bean-discovery-mode 'detected'
> ------------------------------------
>
> Key: CDI-420
> URL: https://issues.jboss.org/browse/CDI-420
> Project: CDI Specification Issues
> Issue Type: Bug
> Components: Packaging and Deployment
> Affects Versions: TBD
> Reporter: Mark Struberg
>
> This is for some future CDI release.
> We currently only have 3 bean-discovery-modes
> * none
> * all
> * annotated
> The spec also currently says that ProcessAnnotatedType will only get fired (12.4) for
> • each Java class, interface or enum deployed in an explicit bean archive, and
> • each Java class with a bean defining annotation in an implicit bean archive.
> • each session bean
> Which means that we do not get the ProcessAnnotatedType (PAT) event for any class in an 'annotated' or 'implicit' BDA which does _not_ have a bean defining annotation.
> It might be useful to fire the ProcessAnnotatedType for all classes, but do not pick them up as Beans if they (after PAT) do not have a valid scope. Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing.
> I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea...
