Hi Charles,
Weld uses Pax CDI provided BundleResourceLoader[1] to load classes in an
OSGi bundle. It loads only those that are discovered by BeanScanner[2].
When you call getBeans() Weld does not load the parameter class anyhow
since you already provided a loaded class. Weld will try to match the
type you pass to getBeans() with the types of beans it had loaded.
