Wow, guys, you are seriously concerned about the copyright issue, as I see
It seems so meaningless to me
What do you afraid of? That Sun will steal your priceless code? I doubt they need it. And if they will, how you will know? And if you will found out, what you gonna do? Sue them? You, small and lonely SCJD (I bet you'll pass), against the mighty law machine? The one, which kicked BG's ass? Come on, don't you have more serious issues to solve in the assignment?
P.S. The post above is totally copylefted by me
P.S.S. It doesn't intend to insult. I am respectful for everybody�s work, I just don't think the magic word will make it more protected. Sorry if I made someone angry
