This loaded just fine for me on OSx with java 1.8 And on linux boxes with Java 1.8

Maybe just doesn't work in java 1.9 yet.

Doesn't work with Java Verions > 1.8. Which is quite bad as 1.8 is already out of support...

Yea, I'm getting the error with java 11. This dependency is needed for gitlab integration, seems I'm going back to using a 6 year old JVM again...
