Gilles commented on MATH-542:
-----------------------------
I think that the most interesting use of the new functionality (as I see it)
might be to do away with exception wrapping. In particular, this would apply in
the controversial example in "ContinuedFraction".
We don't need a "ConvergenceException": A high-level message (conveying
convergence failure) can be attached to the low-level exception (description of
the failure).
> Allow the addition of multiple messages to the exceptions generated by CM

> Key: MATH-542
> URL: https://issues.apache.org/jira/browse/MATH-542
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Gilles
> Assignee: Gilles
> Priority: Minor
> Labels: api-change
> Fix For: 3.0
>
>
> Borrowing on the idea of "ExceptionContext" implemented in [Lang],
> "MathRuntimeException" (base class of all exceptions generated from CM) will
> be enhanced so that an unlimited number of (localized) messages can be added
> to an exception object.
> The "MathThrowable" interface (implemented by "MathRuntimeException") will
> contain the following new method:
> {code}
> /**
> * Sets a message.
> *
> * @param pattern Message pattern.
> * @param arguments Values for replacing the placeholders in the message
> * pattern.
> */
> public void addMessage(Localizable pattern,
> Object ... arguments);
> {code}
