Sebb commented on MATH-701:
---------------------------
If lazy init is dropped, then the rand field can be made final.
Can secRand be made final? This would mean dropping setSecureAlgorithm() in
favour of an extra ctor.
Since secRand is not always needed, this is an argument for making the secure
stuff a sub-class.
Alternatively, IODH could perhaps be used with secRand.

> In "RandomDataImpl":

> rand.setSeed(System.currentTimeMillis());
