I didn't mean for this new exception to be used everywhere. We were specifically trying to avoid just issues with the commit message here.

Looking more at this, communicating through an exception seems wrong. The visitor already has a way to communicate problems through the addFailureMessage method. We should just stop throwing exception and treat this as any other "normal" failure.

Please break this long line.
