Two problems with this though: * a forbidden apis check fails (saying that RandomizedRunner's random() should be used instead but i'm unclear still on how that might be done) * the tests no longer pass, which baffles me though haven't looked at details yet; speculations: * was the randomness in the tests predictable before and now it's predictable also but the number sequence has changed and test expectations need to be adjusted to match? * something to do with order of system property setting and non-test/test class loading perhaps and perhaps use of the RandomizedRunner's random would solve it somehow? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
