OK, so this is my stance:

* Unless Fedora can sign the jars that we build from source, this is a

We cannot permit pre-generated signed jars. I've seen too many
horrifying java crapboxes stuffed full of proprietary components,
ancient components, and illegal components to simply permit this under
any conditions. If it doesn't build from source, we aren't shipping it.

Now, I would be interested in hearing whether we can do this with
IcedTea or not, and if so, how to accomplish it. This seems like it
would be a very necessary component to the non-existent Java packaging
