The new standalone ecj package, and corresponding new eclipse build need to be tagged into F11 Beta. The standalone package will prevent small java packages from pulling in gnome and mozilla. Correspondingly, a new eclipse build was needed, since ecj used to be a part of the the eclipse build before.

ecj build: http://koji.fedoraproject.org/koji/buildinfo?buildID=93728
eclipse build: http://koji.fedoraproject.org/koji/taskinfo?taskID=1235571
