I am using Rome 1.0, and I am working with multiple versions of RSS.
It seems that when multiple links are used within a channel, only one is detected.
It looks like this issue was already fixed for Atom (https://rometools.jira.com/browse/ROME-64?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#issue-tabs) but not for RSS.
Using the same example as used in the above link:
SyndFeedInput input = new SyndFeedInput();
SyndFeed nativeFeed = input.build(new XmlReader(inMess));
nativeFeed.getLink() returns the first link, but nativeFeed.getLinks() returns an empty list.
