Hi,
I haven't been able to update Fedora 7 w/ yum for about two weeks now because gcc-java update seems to require eclipse-ecj (more specifically, /usr/share/hava/eclipse-ecj.jar) but isn't able to install eclipse-ecj package.
I've reopened an old PR on this: https://bugzilla.redhat.com/show_bug.cgi?id=231591
