Problem/Bug Can't get my bukkit server to run. Bukkit 1.11.2

I've been trying to start my bukkit server for me and my friends but it's not working.
When I run the batch file this is what I get and it only creates the logs folder.

I was using this server for probably more than 2 weeks and I had never got this problems...

I've tried to download the craftbukkit.jar again and deleted all the files, but nothing helped. My Java is up to date, and for now only restarting PC helped, but after closing and opening again, got the same log/problem.

Thanks in advance!



(Attached crash report)
