I was trying to start a 1.16.5 modded server and it worked fine during startup, but as soon as it started the console filled up with errors and it crashed after a little while. I'm using the latest version of MCMT on forge 35.1.37
heres the logs: latest.log

Yeah, you should downgrade to JDK 8. For me it's much better, cuz it has CMS gc. JDK 8 should help with this Nashorn thing

Thanks a lot! that fixed the issue. Server runs fine now :D

No problem. Have a very performant server.
If you want to talk or whatever you can add me on discord KubiRemPL#6064

Can you use java 8?

do you mean JDK 8? Mine seems to be on JDK 11 right now. Do i need to downgrade?
