Minecraft doesn't need Java anymore.

One of the big complaints Minecraft players have is that Minecraft runs on Java — it’s a pain to deal with because it’s insecure and needs frequent updating to avoid exploits, and they’d rather not deal with it at all. Thanks to a new launcher, Minecraft no longer requires you to install Java, so you can finally remove it.

The short version is that Minecraft is now bundling a standalone version of Java into their installation and it doesn’t have the security problems and annoyances that regular Java does.

Could still have "security holes".

Yes it could do Willy, but they won't be as big as the ones with 'ordinary' Java :)

Good! I think Minecraft was my last reason for keeping Java
