    023 * A specialized implementation of {@code FileLocationStrategy} which uses the
    024 * passed in {@link FileSystem} to locate a file.
    025 * </p>
    026 * <p>
    027 * This strategy implementation ignores the URL of the passed in
    028 * {@link FileLocator} and operates on its base path and file name. These
    029 * properties are passed to the {@code locateFromURL()} method of
    030 * {@code FileSystem}. So the burden of resolving the file is delegated to the
    031 * {@code FileSystem}.
