[weld-dev] Issue with weld 2.1.0.Final on OSGI

[Jozef Hartinger]

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.
