[MC-998] Error loading MinecraftLauncher.jar / Could not get the JAWT interface

I can not run minecraft using the .jar launcher.
Running Minecraft using the normal launcher always causes it to use java 6 even if you have a newer version installed. Running through the .jar launcher crashes on a black screen as soon as I log on. It gave a LWJGL exception.
