[MC-152049] Exception in server tick loop: java.lang.IncompatibleClassChangeError

Running Vanilla 1.14.1 server on fully patched Ubuntu Server 18.04, with one i5-6500 core allocated to the VM and 2048MB of RAM. This crash crashes the server. I initially had some issues running a similiar configuration (using MC 1.14 on CentOS 7 Minimal), but switching to Ubuntu seemed to have fixed it.

Crash log is included below.
