Hi, sorry if I'm doing something wrong, I'm new to these forums, and to forge in general. I just installed forge, and when I start it up it crashes and I get the following message:

I have tried a few fixes, but none of them worked. Please help me!

Same error with me.

Just installed minecraft v1.9.4 and Forge 1.9.4.

Looks like some problem with the latest Java 8u91.

1.9.4 builds were temporarily broken, re-download should be fine now. Make sure you've cleared you cache before redownloading.
