When using NormalDistributionImpl calss, I encounter the error throwing message
org.apache.commons.math.ConvergenceException: maximum number of
iterations reached

The value provided in cumulativeProbability is a double of current
time subtracting previous timestamped e.g. t_now - t_prev
What might cause this issue or how to fix it?
Thanks.
