Subject [jira] [Updated] (MATH-899) A random crash of MersenneTwister random generator
Date Fri, 16 Nov 2012 09:54:12 GMT

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.
