> I proposed to create a base class which the existing abstract classes {{AbstractRandomGenerator}} and {{BitsStreamGenerator}} will extend.
> This would allow to define {{nextBytes(byte[])}} at the base class level.
> The code for that method is almost identical in the two hierarchies: they only differ in a call to either {{nextInt()}} or {{next(32)}} respectively; the latter is however the same as the former, in disguise, and is not subject to change given the type of return value.
> As a corollary, the new base class can be the unique place where to add utilities such as the one proposed in MATH-1306.
> *Update:* {{AbstractRandomGenerator}} and {{BitsStreamGenerator}} are both obsoleted by the class proposed in this report.
