S=C3=A9bastien Brisard commented on MATH-699:
----------------------------------------

I've realized that boundary cases ({{p =3D=3D 0}} and {{p =3D=3D 1}}) are n=
ow handled correctly: concrete instances of {{AbstractRealDistribution}} no=
 longer need to override this method, which are removed in rev {{1210756}}.

> This bug report follows MATH-692. The attached unit test fails. As requir=
ed by the definition in MATH-692, the lower-bound of the interval on which =
the cdf is constant should be returned. This is not so at the moment.
