Alexander Nozik updated MATH-899:
---------------------------------

    Description: 
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.

UPD: The problem most probably arises only in multy-thread mode.
