Same issue
Don't mark it as a duplicate as the other issue has been marked invalid. Thanks.
I have the newest version of Java and it still crashes.
[CODE=Error]

Maybe look at the error log? The error occurs in minecraft classes, not in optifine or spigot.
So I have to attach game output AND crash report.
I will do it as fast as I can.
When it will be fixed?
P.S. I searched on my problem but I couldn't find a report with exactly the same problem
Still not fixed
