John Fang updated STORM-1650:
-----------------------------
Description: '''Implement a random number generator based on the XORShift
algorithm discovered by George Marsaglia. This RNG is observed 4.5 times faster
than {@link Random} in benchmark, with the cost that abandon thread-safety. So
it's recommended to create a new {@link XORShiftRandom} for each thread.'''
