forge 1.7.10 works on minecraft 1.7.2?

i have java 7 :c

You're running java 8 hence why you're getting the error.

Update to Minecraft 1.7.10 there is no reason not to. If a mod hasn't updated by now it wont update and you should drop it.

If you don't want to update, we will not support you.

These are the rules to keep everyone sane.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Dont bullshit me there is LITERALLY NO WAY to get this EXACT error on 1.7, 1) IT HAS THE VERSION OF JAVA IN IT and 2) Its caused by 1.8 changes.
