Karl Heinz,
Thanks for your reply. Unfortunately, I can't reproduce this failure locally. I run:
mvn -Prun-its clean verify
And all the integration tests pass:
Passed: 20, Failed: 0, Errors: 0, Skipped: 1
I know, "works on my machine"... . But could you check out my branch and try building it, too?
What makes me think that this isn't necessarily related to my change is that e.g. this other PR also fails with the same problem:
So maybe it's some issue specific to the CI environment?
