Alexander Nozik commented on MATH-899:
--------------------------------------
The synchronized wrapper works fine. I can not guarantee that it does not
produce error at all because I made only finite number of runs, but no errors
so far.
> A random crash of MersenneTwister random generator

> There is a very small probability that MersenneTwister generator gives a
> following error:
> java.lang.ArrayIndexOutOfBoundsException: 624
> in MersenneTwister.java line 253
> The error is completely random and its probability is about 1e-8.
