I recently changed the Ant RPM's Release header from 2fc to 0jpp_1fc in rawhide: https://www.redhat.com/archives/fedora-cvs-commits/2005-November/msg00159.ht...
Thus, the Ant RPM went through the following three consecutive versions in rawhide:
ant-1.6.2-3jpp_14fc ant-1.6.5-2fc ant-1.6.5-0jpp_1fc
If you had already updated your rawhide box from ant-1.6.2-3jpp_14fc to ant-1.6.5-2fc, you won't be able to yum update it to ant-1.6.5-0jpp_1fc, because 0jpp_1fc is less than 2fc as far as rpm is concerned. Functionally, there are currently no differences between these two releases.
The reason I had to change the release number was to make it possible to resync Fedora's Ant with the future ant-1.6.5-1jpp RPM from JPackage. To undo my screwup, you may have to run the attached script.
I apologize for the inconvience.
