             Summary: Welcome module (RSS) feed broken in donation
                 Key: NETBEANS-112
                 URL: https://issues.apache.org/jira/browse/NETBEANS-112
             Project: NetBeans
          Issue Type: Bug
          Components: ide - Welcome

In Apache NetBeans the RSS feeds in Welcome Page no longer works. Works on current hg main-silver and works in NB 8.2.

The problem occurs when the downloaded XML has a doctype declaration:

{code:xml}
<!DOCTYPE rss PUBLIC "-//Netscape Communications//DTD RSS 0.91//EN" "http://my.netscape.com/publish/formats/rss-0.91.dtd">
{code}

There used to be a "registered" DTD for this in the Welcome module but it was removed as part of Oracle's cleanup prior to donation. This is why it works on current hg main-silver, but not on the donated code.

See:
http://hg.netbeans.org/releases/rev/66633aaa2811
http://hg.netbeans.org/releases/rev/00ff3249694f

Because of the removal, the XML Reader will - in the absence of a registered DTD - attempt to download the DTD from the Internet, i.e. it will attempt to download http://my.netscape.com/publish/formats/rss-0.91.dtd, which will fail because it redirects to {{aol.com}} and there isn't a DTD at that location. (duh!, I'm actually surprised that {{netscape.com}} still exists and forwards to {{aol.com}}, it's been 18 years since the acquisition !)

The RSS feed from planetnetbeans.org (right side of screenshot) doesn't have a DOCTYPE declaration which is why it works.
