"Bar extends Foo"
The problem is that both Bar and Foo are added as AnnotatedType against ClassTransformer,
and eventually deployed as such.
But WeldClassImpl::superclass is looked-up against ClassTransformer::classes --> diff
WC_Foo instances

OK, fixed in my weld-912 branch:

With this just remember that there can be >1 WeldClass per real class!

class!
Sure, but I think we shouldn't wrap existing WeldClass impls -- else we end-up with
dups.
(unless we then properly impl equals/hash, which is a pita in this case ...)
I've added this to ClassTransformer:
public <T> WeldClass<T> loadClass(final AnnotatedType<T> clazz) {
// don't wrap existing weld class, dup instances!
if (clazz instanceof WeldClass) {
return (WeldClass<T>) clazz;
} else if (clazz instanceof ForwardingAnnotatedType &&
((ForwardingAnnotatedType) clazz).delegate() instanceof WeldClass) {
ForwardingAnnotatedType fat = (ForwardingAnnotatedType) clazz;
return (WeldClass<T>) fat.delegate();
} else {
return (WeldClass<T>) annotatedTypes.get(clazz);
}
}
