I don't play in 1.6.4 anymore, but I want to test a few of my modded worlds in 1.6.4, but when I tried to play the game, it crashed and gave me this:

It doesn't show in an "Crash Report" tab, but rather in the "Game Output" tab. The game shows to load somethings, the launcher briefly disappears, then reappears with this. It wont let the game launch.
Exactly as I said. Install java 7. Click on your MC launcher (the thing where you hit play), click edit profile and you'll see java executable file path, change it. It'll be exactly the same as 7 except for the folder that has version name in it so go to folder one above that one in the path, figure out the name for the java 8 one and substitute. Save profile and hit play. Don't know what else to tell you.

I have the following mods installed:
Custom NPCs
Ars Magica 2
Millenaire
More Player Models
Mr. Crayfish's Furniture Mod
More Enchantments
Light Bridges and Doors
Eternal Frost
Dota 2 Items
Carpenter Blocks
Bibliocraft
Mutant Creatures
Optifine
Twilight Forest
How do I do that?
I know that wont work. I replace all proper mods with the 1.6 versions. See this similar post of mine: http://www.minecraftforum.net/forums/support/modded-client-support/2290169-forge-minecraft-wont-launch
Also, if that WAS the case, it would generate a crash report. But the game didn't. The thing that I pasted game from the Game Output tab.
