That link was broken a little while back also (earlier this week, late last week??? can't remember exactly when). But it seems to be working now. Though I dislike having to hunt for the download I want on the huge list of downloads that Source Forge lists. Yuck. I've heard that this was a Source Forge change which has caused some issues.
Yeah, the SF downloads have been a mess for more than a week now. The SF software upgrade triggered various issues including the file download issues. All JBoss downloads are available on one large single page making it difficult to get hold of the correct one. SF developers are tracking these issues through their bug tracker.
