Luc Maisonobe resolved MATH-440.
--------------------------------
Resolution: Fixed
FunctionEvaluationException, DerivativeException and MatrixVisitorException
have been deprecated in 2.2 and all their use replaced by the new unchecked
MatrixException. A smooth transition patch has been set up in the API to help
user switch to the new scheme with a 2.2 version that is compatible with both
2.1 and 3.0.
The exceptions have been removed in 3.0.
Fixed in subversion repository as of r1037327 for branch 2.X and as r1037328
for trunk (3.0)
> Introducing a "UserException" class

> Key: MATH-440
> URL: https://issues.apache.org/jira/browse/MATH-440
> Project: Commons Math
> Issue Type: Improvement
> Reporter: Gilles
> Assignee: Gilles
> Priority: Minor
> Fix For: 2.2

>
> After a discussion in MATH-425, it was concluded that a new "UserException"
> could be created and advertised as a privileged channel to convey failure
> information through the CM code layer.
> The usage of this exception is the same as the one intended for the current
> {{FunctionEvaluationException}}, {{MatrixVisitorException}} and
> {{DerivativeException}}, so those classes will be deprecated.
