> Environment: Mac OS X 10.9 and also Linux 3.4 kernel; Java 7; Maven
> 3.1.1
> Reporter: Sean Owen

> I see two test failures, in both the copies of BOBYQAOptimizerTest:
> {code}
> Failed tests:
> BOBYQAOptimizerTest.testAckley:209->doTest:282->doTest:338 expected:<0.0>
> but was:<1.047765607609108E-8>
> BOBYQAOptimizerTest.testAckley:208->doTest:281->doTest:336 expected:<0.0>
> but was:<1.047765607609108E-8>
> Tests in error:
> BOBYQAOptimizerTest.testDiffPow:187->doTest:282->doTest:322 »
> TooManyEvaluations
> BOBYQAOptimizerTest.testDiffPow:186->doTest:281->doTest:326 »
> TooManyEvaluations
> {code}
> (This predated the patches I've worked on so I don't think it's me!)
> I tried on Mac OS X and Linux and see the same, so don't think it is an
> environment issue. I'll see if a little digging can uncover the issue from a
> recent commit.
