Hello @chris-day,
Thank you for your issue. I looked into it and currently cannot reproduce your issue. Both, on travis and on my own machine I cannot trigger the same error you are getting.
Can you provide more information? Which maven and Java version are you using? On what kind of OS?
At least some parts of the error message seem to be an issue with the used Java version. This project needs at least Java 11.

Hi Jan – Thanks for getting back so quickly – I was using Java 8. I’ll retry with Java 11.
