java 8 is already in the main repos and had been there since F-19.
It's just not providing things like java-devel and hence isn't used by
default in the build process.

That's not an advantage, building ARM packages is a requirement of
something in primary architecture. Also you can't tag copr builds in
Fedora. You need to use a koji f21 side tag.

Well there will also be a mass rebuild in general for gcc 4.9 so you
should coordinate with rel-eng to minimise builds in general.
