[READ BEFORE MOVING] Forge 1.8.0 not launching

[MTMaster]

Before someone moves this, please note that forge 1.8.0 IS NOT supported anymore, so if it gets moved to bug reports it will get locked. I would like to know if the community has any suggestions for me.

 

For some reason I cannot launch my forge. This is the error that appears. Any suggestions?
