the build failed again on H10; exactly the same tests failed as before: This test: https://builds.apache.org/job/Commons%20Math%20H10/1/console Previous failure: https://builds.apache.org/job/Commons%20Math/14/console --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
