[jira] [Created] (MATH-1020) "nextPermutation" method broken (in class "o.a.c.m.random.RandomDataGenerator")

Gilles created MATH-1020:
----------------------------

             Summary: "nextPermutation" method broken (in class "o.a.c.m.random.RandomDataGenerator")
                 Key: MATH-1020
                 URL: https://issues.apache.org/jira/browse/MATH-1020
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.2
            Reporter: Gilles
             Fix For: 3.3


Correct behaviour of this method relied on the [broken behaviour of "shuffle"|MATH-1019].
With a fixed "shuffle", the "nextSample()" unit test caught the bug in this method.
