World Bug [Java?]

http://pastebin.com/LDdn4L31
So I've been restarting Minecraft a LOT Lately, And i was going to test things out when all of a sudden when i went into the world, All it said was "Loading, Building terrain" Then it Fogged up {Because that is what happens when Things don't load for me} And it went to the crash page.
I Put a Pastebin link so You could see ALL The results.

If there is any way to fix this Yes, Please I Need the help. This happened RIGHT AFTER I Restarted it Once again. I Can't Repair it from the control panel for some reason. I WILL Create a video for a better 'Vision' Of it.

Any help would be appreciated!
