Problem adding a source to BulkDownloader

[mustberuss]

I tried to add the file of withdrawn patents to sources.xml using the url tag but it didn't work.

    <source>
        <name>USPTO</name>
        <type>WITHDRAWN_GRANTS</type>
        <download>
            <url>https://www.uspto.gov/sites/default/files/documents/withdrawn.zip</url>
            <count>1</count>
    </download>
    </source>

It did work when I changed the xml tag to url2 and added an additional annotated setter in SourceDownload

    @XmlElement(name = "url2")
    public void setDownloadUrl2(String downloadUrl) {
        this.downloadUrl = HttpUrl.parse(downloadUrl);
    }

It also worked with a scrape of https://www.uspto.gov/patents-application-process/patent-search/withdrawn-patent-numbers but I couldn't figure out why the url tag and annotation didn't work.

The grant xml files can contain data for patents that were subsequently withdrawn.
