------------------------------------
Hello,
Sorry to post a message on this Resolved bug, but I appear to have the exact
same problem with commons-math3-3.2. Here are the interesting parts of my Maven
output:

I am using Fedora 20 x86_64 with kernel 3.12.7 and with
java-1.7.0-openjdk-1.7.0.60-2.4.4.1.fc20.x86_64.
> BOBYQAOptimizerTest has two failing tests

> Key: MATH-1057

> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.2
> Environment: Mac OS X 10.9 and also Linux 3.4 kernel; Java 7; Maven
> 3.1.1
> Reporter: Sean Owen
> Priority: Minor
> Fix For: 3.3
>
> Attachments: MATH-1057.patch
>
>
> I see two test failures, in both the copies of BOBYQAOptimizerTest:
> {code}
> Failed tests:
> BOBYQAOptimizerTest.testAckley:209->doTest:282->doTest:338 expected:<0.0>

> 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.
