If a class can't be loaded by the classloader then I can't see how Weld would end up with the Class object to pass to loadBeanDeploymentArchive...
In that case, the "is reachable check" is pointless and I'm replacing the current implementation of loadBDA by one that uses a singleton map of CL->Archives.
How did we then decide to handle library archives?
Or, actually, how did you implement it?
Or what happens if you push in a java.* Class instance into this loadBDA method?
