Robert Metzger commented on FLINK-17040:
----------------------------------------
Thanks a lot for looking into this issue.
Regarding Azure: The build for the pull request failed because the git checkout
failed. Sadly, flinkbot showed "SUCCESS", even though the build was not
successful. I will look into it.
The Travis build failed in the library (so it correctly found the issue). I'm
pretty sure Azure would have found the issue as well, if the checkout would
have worked.
