Note that the return value of java.util.ServiceLoader#load is an
iteration over the
result of a call to ClassLoader#getResources.
The only effect of setting "delegate" to false is that any local
matching resources will appear
*first* in the returned Enumeration, but it does not mean that any
matching resources higher
up in the class loader delegation chain will be omitted from the
Enumeration.
