If you're dreaming, then I'm dreaming the same thing.
That said, I think I read somewhere that Sun had dropped support for 1.4 (is that true or I am dreaming it?). If this is true it might be good to continue supporting 1.5. I guess we need to check if there are any users out there who absolutely require 1.4 in production. We might want to have a special build for them while making the standard build work on 1.5.
