MATH-1535: Recurring issue with method "fixTies" (WIP).
...
Current code is too fragile:
* Adding "jitter" does not work reliably.
* Changing the seed of the RNG make unit tests fail.
This commit includes:
* Changing from "MathInternalError" to "MaxCountExceededException".
* Using named variables for hard-coded values.
* Adding unit tests (set to "@Ignore" to let the build pass).
* Handling infinite values to avoid creating NaN values.

MATH-1531: Avoid spurious exception.
...
In the provided use-case, computation resulted in a value slightly above 1,
thus throwing an exception (invalid probability).
Workaround replaces the value by 1 when it is up to one ULP away.
