Thomas Neidhart commented on MATH-1057:
---------------------------------------
Ah ok, now I get the same error, strange that I did not see it before.
In this case I think it would be fine to change the epsilon to 1e-7 but I would
like to understand why we get different results for jdk 1.5 and 1.7 here.
> BOBYQAOptimizerTest has two failing tests

> 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.
