$ rpm -qf /usr/share/java/jaxp_transform_impl.jar saxon-9.3.0.4-5.fc18.noarch xalan-j2-2.7.1-17.fc18.noarch one of the 2 is not needed, but I do not know which one.
This jar file is managed by alternatives and is therefore packaged as a %ghost symlink by both packages. See the guidelines here: http://fedoraproject.org/wiki/Packaging:Alternatives If you wish to use an alternative implementation for jaxp_transform_impl, please run: $ su -c 'alternatives --config jaxp_transform_impl' As far as I can tell both packages are correct, so I am going to close this bug. Please re-open if you feel differently.
