Subject [jira] Commented: (MATH-361) Localization and Error Handling
Date Wed, 16 Jun 2010 00:36:23 GMT


Phil Steitz commented on MATH-361:

I agree with the following points from the discussion above.

1. We need to continue to support localization.
2. We should not introduce an external dependency if it doesn't make things significantly
easier for us or our users.
3. Luc's proposal for cleaning up localization support is no more work and does not appear
to be any harder to maintain than Gilles' proposal to use cal10n.
4. We should refactor our exception hierarchy over time, moving some of what is now in messages
into exception state / typing.
5. Exception refactoring needs to be done with consideration for users of the existing exceptions.

So I would say go ahead with Luc's last suggestion - make the enums change and then separately
address the exception hierarchy.  It would probably be best to open separate tickets for the
exception hierarchy changes.
