I have a friend who has a high position in a huge company that is Java-only. I asked him just the other day about the situation and pretty much he said there were no alternatives to Java in many sectors, especially banking. "If they make it a paid platform, everyone will just pay". Pretty much they aren't worried even a bit. Also, seeing how well Oracle (database) is used in corporate environments - I think Java is going to do just fine (in corporations), but it might get slightly out-of-reach for common developers.
