Gilles resolved MATH-349.
-------------------------
Resolution: Fixed
Removed deprecated code. Classes are now immutable.
> Dangerous code in "PoissonDistributionImpl"
> -------------------------------------------
>
> Key: MATH-349
> URL: https://issues.apache.org/jira/browse/MATH-349
> Project: Commons Math
> Issue Type: Bug
> Reporter: Gilles
> Priority: Minor
> Fix For: 3.0
>
>
> In the following excerpt from class "PoissonDistributionImpl":
> {code:title=PoissonDistributionImpl.java|borderStyle=solid}
> public PoissonDistributionImpl(double p, NormalDistribution z) {
> super();
> setNormal(z);
> setMean(p);
> }
> {code}
> (1) Overridable methods are called within the constructor.
> (2) The reference "z" is stored and modified within the class.
> I've encountered problem (1) in several classes while working on issue 348.
> In those cases, in order to remove potential problems, I copied/pasted the
> body of the "setter" methods inside the constructor but I think that a more
> elegant solution would be to remove the "setters" altogether (i.e. make the
> classes immutable).
> Problem (2) can also create unexpected behaviour. Is it really necessary to
> pass the "NormalDistribution" object; can't it be always created within the
> class?
