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}} (?)).
