Alexander Nozik commented on MATH-899:
--------------------------------------
I always can insert new version of the generator in the test program where I
have found the problem in the first place. Still I don't know what conditions
are required to error for occur. For now I'm using a JDKRandomGenerator and it
works just fine so far.
