Please see bug 1022897 for a description of the problem. Once jline1 is in rawhide, jline should become what's jline2 now (minus compat bits). After that jline2 should get retired (since it'll be succeeded by jline).
Mat was kind enough to grant me jline commit access. I'm going to switch jline to 2.x now.
jline 2.10 has been build in rawhide: http://koji.fedoraproject.org/koji/taskinfo?taskID=6113156 Closing this bug.
