The Download runtime UI offers many versions of EAP, but it seems that not all of them are valid.
I'm not sure if all of this is taken from stacks, if so, a JIRA with JDF will be required as well.

When you open Preferences -> JBoss Tools -> JBoss Runtime Detection
and click Download..., you're offered JBoss runtimes for download.

In the list, there are these EAP versions:
JBoss EAP 6.0.0
JBoss EAP 6.0.1
JBoss EAP 6.1.0
JBoss EAP 6.2.0

6.0.0 and 6.0.1 are listed as manual downloads and if I want to download them, I am offered this link:
http://www.jboss.org/products/
From there, I can get to https://www.jboss.org/products/eap/download/
The oldest version of EAP this contains is 6.1.0.
Probably the only place to get older EAP is access.redhat.com.
So we should either remove these older versions from the list (I would prefer that) or link to access.redhat.com.

Then there is 6.1.0 and 6.2.0, both available through the Download Manager, which is fine. But the site also contains 6.3.0.Beta so we might offer that, too?

The same applies to Portal - we list JPP 6.0.0 and point users to jboss.org/products. But that only offers JPP 6.1.0. So I would vote for removing the JPP 6.0.0 entry.

And last, WildFly 8.1.0.Final is available, so we should add that.
