Luc Maisonobe commented on MATH-446:
------------------------------------
I'll prefer simply propagate the more specific exception.
One way to be sure of what may be propagated is to temporarily have
MathIllegalArgumentException, MathIllegalStateException,
MathArithmeticException extend a checked rather than an unchecked exception,
then fix the throws/javadoc and then revert the exception back before commit.
This is how I handled FunctionEvaluationException, MatrixVisitorException and
DerivativeException ; it was much easier and less error-prone than reading code.
> New exceptions to replace those in package "special"

> Key: MATH-446
> URL: https://issues.apache.org/jira/browse/MATH-446
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Gilles
> Priority: Minor
> Fix For: 3.0
>
>
> Classes in this package uses deprecated exception objects
> ({{MaxIterationsExceededException}}).
> Also, many methods have signatures that contain the checked "MathException".
> It should be removed.
> We can either let the {{MaxCountExceededException}} propagate, or wrap it
> into a more general type ({{MathIllegalStateException}} (?)).
