griffon.core.GriffonExceptionHandler - Uncaught Exception
Created by: ashleysommer
Getting this error when I try to launch muwire OS: Ubuntu 18.04 I've tried MuWire version 0.4.7 and 0.4.11, both give the exact same problem I've also tried JAVA implemetations: Oracle JDK 1.8, OpenJDK-1.8, and OpenJDK-8, (because I happened to have each of those already installed on my system), it fails with exactly the same message.
$> java -Dgriffon.full.stacktrace="true" -jar ./MuWire-0.4.11.jar
