Gilles commented on MATH-1404:
------------------------------

This test can fail with probability 0.01 even if the distribution of the random \
numbers is uniform.

If you run the test several times, you should get successes and failures that are not \
correlated to the local settings.

> Key: MATH-1404
> URL: https://issues.apache.org/jira/browse/MATH-1404
> Project: Commons Math
> Issue Type: Bug
> Reporter: Karl Richter
> 
> Specifying `LC_ALL=en_US.UTF-8` causes test failures like \
> `RandomUtilsDataGeneratorJDKSecureRandomTest>RandomUtilsDataGeneratorAbstractTest.te \
> stNextLongNegativeRange:99->RandomUtilsDataGeneratorAbstractTest.checkNextLongUniform:130 \
> Chisquare test failed p-value = 0.0082266579945659 chisquare statistic = \
> 25.304000000000006.` which don't seem to occur with `LC_ALL=de_DE.UTF-8`, see \
