ROME gives me a error regarding DOCTYPE, but there is no DOCTYPE tag in my XML

I'm using ROME to read some RSS feeds. It turns out I'm getting the error below:

Caused by: org.xml.sax.SAXParseException: DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

However, the XML I'm trying to read from has no DOCTYPE at all.

<?xml version="1.0" encoding="UTF-8"?><rss version="2.0"
    xmlns:content="http://purl.org/rss/1.0/modules/content/"
    xmlns:wfw="http://wellformedweb.org/CommentAPI/"
    xmlns:dc="http://purl.org/dc/elements/1.1/"
    xmlns:atom="http://www.w3.org/2005/Atom"

    xmlns:slash="http://purl.org/rss/1.0/modules/slash/"
    >

<channel>
.
.
.
</channel>
</rss>

I already tried do use the

            SyndFeedInput input = new SyndFeedInput();
            input.setAllowDoctypes(true);

I got another error, though.

Has someone faced the same error?

Thank you.

I had the same problem. I tried getting the document with curl and found out that it was a redirect:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>Redirecting...</title>
<h1>Redirecting...</h1>
