integration tests are not run in Travis / CI currently

I can't recall if this was on purpose, but I noticed today that the Travis CI build only runs mvn test (example).

Running mvn verify locally I get a test failure in:

regarding this specific test, I went back and tried a few old versions to see where it broke:

• 0.1.0 with java8 - test passes
• 0.1.5 with java8 - test passes
• 0.1.5 with java11 - test fails

I haven't tried other versions yet to narrow it down / fully bisect it yet
