Hi @strangelookingnerd,

Thank you for raising the PR.
I will get to it in the next weeks. But before that I will trigger our tests so I can give you early feedback on this.

Best,
Yana

@strangelookingnerd, I wanted to trigger the tests against this branch but the build is failing.
Could you have a look at it? In repo root:

mvn -s clean source:jar deploy source:test-jar com.mycila:license-maven-plugin:check -Pdistro,distro-ce,distro-wildfly,distro-webjar,h2-in-memory

Error that I see:
