I was a pretty strong advocate of Java at one point, believing it would eventually be freed, that multiple competing, but mostly compatible, implementations would be created, that it would eventually run on both the smallest and largest systems, and that over time the industry would standardize on it. Except for the last, all of the above have arguably come true. So why do I now avoid it like the plague?
It is very sad. Java had the potential to become the lingua franca of the entire software universe, and a darn good one at that. It didn't, and now that Oracle has gone all lawsuit-happy over it, I just don't see anyone with a choice in the matter ever wanting to touch it again.
If you were a national of a country that had invaded mine, for no lawful reason, and had murdered hundreds of thousands if not millions of my fellow countrymen, not just soldiers trying desperately to protect it, but innocent civilians as well, sometimes for sport, I would advise you very strongly not to come here, and if you were already here, to leave at once. You may not consider yourself to be part of the invading/occupying force, but trust me, there are enough people there who will, and will consider you a completely legitimate target.
Even if you are OK with the risk of dying, consider that you might not die, but maybe lose a few limbs, maybe your eyesight, maybe a part of your brain. Maybe you'll live 60 more years but in constant, agonizing, unbearable pain. Maybe you'll need dozens of expensive surgeries that will bankrupt you and everyone around you. War is not exciting, glorious, pretty, or fun. It is the sum of all evil. Avoid it if you can.
Others have pointed out that there are plenty of interesting, exciting and safe places in the world where you would be welcome, provided you behaved yourself, and would have little trouble finding gainful employment. There are banking, tax, and of course cultural issues to consider, which I'd strongly recommend researching in advance. But it still can be a tremendously enlightening and rewarding experience.
