Load package-info class from nested sources

Right now ConfigurableClassLoader can't load package-info class from nested resources.
Because the URLClassLoader that we extend loads it with UCP, and if .m2 repository isn't found then UCP will be empty.
We reproduce that issue with SalesforceMarketing component (TDI-50955) in a new Microservices mode, when .m2 repository is unavailable (or empty).
Will share here the component, job to reproduce the issue:

-> UCP in URLClassloader point to empty array
-> java.net.URLClassLoader#findClass can't find the resource package-info.class
