Thomas Neidhart commented on MATH-808:
--------------------------------------

Hi,

I could not run your test code as some classes are missing.
Maybe the described behavior is related to a precision 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
