Hi,

I could not run your test code as some classes are missing.
Maybe the described behavior is related to an accuracy flaw that has been fixed in MATH-781
(see https://issues.apache.org/jira/browse/MATH-781). Could you please check if the same problem
occurs with the latest trunk.

For the test case that Gilles mentioned you could take a look at the attached ones from MATH-781.

Thanks,

Thomas
