Forge doesn't launch

Hey guys

 

I'm with a problem with Forge here that is really freaking me out.

I'm new on minecraft and i'm playing about 1 month on single player without mods, now i installed the forge to try some mods, but when i select forge on profile and click play, the launcher restart and i cannot start the game with forge.

 

 

I have Java 6 update 27 x86, but i tried different versions of java here is the list:

 

Java 7 update 9

Java 7 update 25

Java 7 update 51

Java 7 update 55

Java 7 update 71

Java 8 update 25 x86 and x64.

 

I have a 64 bits OS but i tried the two versions. And i tried to delete the .minecraft folder and download again, but i still have the same problem.

I'm using the Keinett launcher version 1.400, tried the new version Shiginima 1.600 and i got the same error.

 

This is the logfile error that appear in Development Console:
