Please see bug 1022897 for a description of the problem. Basically, jline does things the other way around as compat and current packages are supposed to work. A first step is to get jline 1.x packaged as jline1. Then jline2 should become jline.
Review request for jline1 is here: https://bugzilla.redhat.com/show_bug.cgi?id=1022908
There is a jline1 build of jline 1.x in rawhide: http://koji.fedoraproject.org/koji/buildinfo?buildID=473702 Closing this bug. If you are interested in maintaining jline1 please add yourself to the new jline1 package in pkgdb. Thanks!
