I was trying to play my game called Minecraft and I needed a Java update for my Mac. When I tried to update, Java said none are available, so I googled Java6 and downloaded it and installed it. Now when I try to start Minecraft it will begin to open but gives me an error. So, I thought I’d just downgrade back to what I have before. But I can’t open Java at all to do that. It says “A static initializer of the main class threw an exception: java.lang.NullPointerException.” Does anyone have a clue what this means?
