URLPackageScanner prefix not correctly set when Classloader is not set to WAR root

If a modular classloader for a WAR is set with a relative path instead of the root, i.e. starting at 'WEB-INF/classes', then URLPackageScanner.loadResources() successfully finds a resource without a 'prefix' being set.

However, handleArchiveByFile() is then unable to find the class without a prefix being set to 'WEB-INF/classes'
