https://bugzilla.redhat.com/show_bug.cgi?id=1015245 introduced testing against previous EAP versions. Since this was a backport from WildFly, it also included tests against previous versions of JBoss AS. For an EAP DC we don't really care about backwards compatibility to AS/WF versions, so to speed up the tests we should only test against previous EAP versions.
