GreatVoyage-v4.1.1 java error on Ubuntu 20.04.1 LTS (Focal Fossa)

[neshala]

Any idea what I am doing wrong?

1. What did you do?

I have downloaded FullNode.jar (GreatVoyage-v4.1.1) and installed jre and jdk from Oracle (java 11.0.9 2020-10-20 LTS and javac 11.0.9) but when I am getting errors. OS: Ubuntu Server 20.04.1 LTS (Focal Fossa)

2. What did you expect to see?

Active peers and blocks synced

3. What did you see instead?

The following errors:

The JDK version should be Oracle JDK 1.8
