In this context, we know the classPath urls are all unique because they
come from a set. What this logic does is to prepending the entry name with
enough elements of this path to make it unique. I presumed there was some
desire to keep the entry names short for other reasons. By using the elements
from the path we get something guaranteed to be unique while keeping some
meaning to the name.
