Java issues

I have noticed an error with the latest version of Java 8 and the gullivers mod. Yes yes I could have gone to the mod author and talked about it but first I wanna see if its not just me that its happening to because if its just me then Im unable to report it to Uncle Miam as it is an isolated issue and that means it is unable to be resolved by the mod author. So if it is happening to you or you have any idea on how to fix it lemme know. Now if this is isolated I will go Rambo on the coding to see if theres anyway I can fix it as a solo mod encryprioner.

Here is my game output that I'm getting on my launcher if you need that aswell

Unfortunately the only thing I can suggest here is this.

It doesn't look like anything you could fix.  If I had time and access to the codebase, I could probably research it to see what's going on, but I obviously don't have that.
