docs: Obtain the URL to the properties file containing the localized messages given the supplied bundle name. This method is
  responsible for searching to find the most appropriate localized messages given the locale, but does not need to search
  using the {@link Locale#getDefault() default locale} (as that is done by the {@link I18n#text(Object...) calling} method.
  
  @param classLoader the classloader that should be used to load the localization bundles
  @param bundleName the name of the bundle of properties; never null
  @param locale the locale for which the properties file URL is desired
  @return the URL to the properties file containing the localized messages for the named bundle, or null if no such bundle
  could be found
