Hi,
it seams there is an implementation error in InjectionResolver when
resolving @Specializes annotated bean. The problem is in situation, when
there are three producers.
1. Producer X
2. Producer Y
3. Producer Z directly override Y with @Specializes annotation
So there are three candidates that means result.size() == 3; This should
throw AmbiguousResolutionException because even there is a
Specialization there are still two candidate beans X and Z.
In such case the behaviour of the InjectionResolver.findBySpecialization
method is:
-------------
while (it.hasNext())
{
AbstractOwbBean<?> component = (AbstractOwbBean<?>) it.next();
if (component.isSpecializedBean() && component.isEnabled())
{
res.add(component);
}
}
if (res.size() > 0)
{
return res;
}
------------
Because there is exactly one component marked as @Specializes this
one is added to the res and than the res.size() == 1. But the
specification says:
3.3.3. Specializing a producer method
If a producer method X is annotated @Specializes, then it must be
non-static and directly override another producer method Y. Then
X directly specializes Y, as defined in [specialization]
<http://docs.jboss.org/cdi/spec/1.1/cdi-spec.html#specialization>.
If the method is static or does not directly override another producer
method, the container automatically detects the problem and treats it as
a definition error.
In my opinion there is not implemented test if it is direct
specialization and this is a bug. Am I right?
