Hello,
I have a very simple setup where I have classes Foo1 and Foo2 that
implement the Foo interface
public interface Foo {
}
@Default
public class Foo1 implements Foo {
}
@Alternative
public class Foo2 implements Foo {
}
Then a class that gets 2 Foos injected
public class Main {
@Inject
Foo fooA;
@Inject
Provider<Foo> fooB;
@PostConstruct
public void init() {
System.err.println("FooA:" + fooA);
System.err.println("FooB:" + fooB.get());
}
}
If my beans.xml file is empty, then I get 2 instances of Foo1 injected
into the class, as expected.
However, if I add
<alternatives>
<class>Foo2</class>
</alternatives>
to my beans.xml, then I get an error when I run the application.

This exception happens when I call Provider.get(). I assumed that the
Provider interface would respect the Alternative Qualifiers, but that
does not seem to be the case.
Is this a bug in what I am doing, or a bug in OWB?
Thanks
