I also thought it was a matter of "powerful", but the opposite way ;-) Tests fail very often to me, much worse than on CI, and I always ended up blaming the more powerful environment I'm running them in. FYI I'm unable to complete any test run on master, testsuite just hangs. When it succeeds, I always had more failures than what I see on CI: even while CI has been occasionally happy (like in February), I never had a fully stable build, even when running it on a single thread. Sorry if that wasn't clear, maybe I should complain about it more often :-P Seriously, I just think we can design the tests better. @Dan sure you can reconfigure the CDI pom.xml to override the surefire settings.
