> Only the constructor PoissonDistributionImpl(double) seems to actually work.  All of the others cause a NullPointerException.  The working one creates a default NormalDistribution, but all of the others just leave the member "normal" set to null and cause an NPE in the constructor.  
> I can't even find a work around to construct a PoissonDistributionImpl with both a specified mean and an epsilon, since there is no way to set epsilon after creation and the constructor PoissonDistributionImpl(double p, double epsilon) does not work.
