Of the last 6 runs, only 1 had a problem with unit test failures. All the builds ran on ubuntu3, apart from the failure which ran on H10. This may have some bearing on the result; I don't yet know.
I had a quick look at 2 tests that failed: SimpleRegressionTest.testPerfect SimpleRegressionTest.testPerfectNegative Although the test case has some instance data, these particular tests do not use any, so it does not look like a concurrency issue in the unit test itself. The SimpleRegression class has mutable instance data, but the test cases create their own instance. I don't know anything about the math functions involved, but it looks as though Infinity might result from getSignificance() if getSlopeStdErr() returns 0, as the latter is used as a divisor. Or if the field sumXX is 0 because that is also used as a divisor. Maybe the H10 host has different floating point hardware? I'll try running some more tests on H10. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
