[cdi-dev] [JBoss JIRA] (CDI-232) Relax requirements for built-in Instance

Jozef Hartinger commented on CDI-232:
-------------------------------------
{quote}Do you mean that the current behaviour allow me to put a non valid bean type
(inject Instance<Foo> where no beans exist with Foo type) ?{quote}
Yes. We should not really change the behavior. Even if we were allowed to do so, this is
still a valid usecase. You can have a code such as:
{code}
@Inject Instance<Foo> instance
if (!instance.isUnsatisfied()) {
// use foo
instance.get();
} else {
// use something other than foo
}
{code}
Relax requirements for built-in Instance
----------------------------------------
Key: CDI-232
URL: https://issues.jboss.org/browse/CDI-232
Project: CDI Specification Issues
Issue Type: Clarification
Affects Versions: 1.1.EDR
Reporter: Martin Kouba
Fix For: 2.0 (discussion)
5.6.2. The built-in Instance
{quote}
The container must provide a built-in bean with:
* Instance<X> and Provider<X> for every legal bean type X in its set of bean
types,
* every qualifier type in its set of qualifier types,
{quote}
This type/qualifier requirements seem to be too strict. Maybe we should omit these and
instead force implementation to satisfy every injection point for every legal bean type
and corresponding qualifiers found in application... or something like that. I'm not
sure about the wording.
By the way Weld (2.0.0.Alpha2) does not fulfil these requirements at the moment.
