bean-lookup issue in Context#get(Contextual, CreationalContext)

                 Key: WELD-907
                 URL: https://issues.jboss.org/browse/WELD-907
             Project: Weld
          Issue Type: Bug
          Components: Scopes & Contexts
    Affects Versions: 1.1.1.Final
            Reporter: Gerhard Petracek

this is a very special case which used to work before weld v1.1.1

Set<Bean<?>> beans1 = beanManager.getBeans(MyBean.class);
Class beanClass = beans.iterator().next().getBeanClass();
Set<Annotation> qualifiers = beans.iterator().next().getQualifiers();
Set<Bean<?>> beans2 = beanManager.getBeans(beanClass, qualifiers.toArray(new Annotation[qualifiers.size()]));

beans1 is the same as beans2

that works without problems.

if you use the same in 
  Context#get(Contextual, CreationalContext)
it doesn't work. i haven't looked at the details but it might be due to the performance optimizations.

the following example isn't that useful (so please don't ask for the reason) - it's just the minimal code to reproduce the issue.

public <T> T get(Contextual<T> component, CreationalContext<T> creationalContext)
    Class beanClass = ((Bean<T>)component).getBeanClass()
    Set<Annotation> qualifiers = ((Bean<T>)component).getQualifiers()

    Set<Bean<?>> beans = CdiUtils.getBeanManager().getBeans(beanClass, qualifiers.toArray(new Annotation[qualifiers.size()]));
    //beans is empty

it isn't specified that it should work but it used to work with weld and it also works with owb.
since there is (imo) no reason why it shouldn't work, it would be great if it gets fixed!
