I think I won't be the only one to say, we need a lot more information here to help you.

Since you are asking this in the development section, are you using Oracle, or something else? Which version of forge is not working for you? Do you have any mods installed?

I'm confused what you are actually doing, but maybe that is just me.

1.version: lastest version for 1.6.4
2.java7,jdk1.8.0
3.I have a lot of mods
4.it was working from 1 week but stopped now, idk why, I didnt edited any java options

thanks.

I hope this can help too.

(that is what was in development console)

1) Try using JDK 1.6, Minecraft 1.6 is obsolete so it's best to use versions that match it's age.

2) You're using a coremod, and it could be the problem - fix it

3) Reinstall your Forge workspace

4) Forge for 1.6 is obsolete and not supported anymore, you really should be coding in 1.7.x

EDIT: Maybe it's a mod bug with Arabic. Tried setting computer to English? Just to test?

Quote from Jimmy04creeper»

Does forge run on java 1.8 ? i herd it has issues with it or is it fixed now ?

Recent 1.7.10 versions of Forge support Java 1.8, but 1.6.4 versions only support up to Java 1.7.

ConcurrentModificationException crashes are usually caused by using Java 1.8 with 1.6.4.
