About PropertyDoesNotExistException: We once changed the semantic of our
getXXX(String key) methods to always throw an exception if the property does not
exist. This caused lots of protests by our users who demanded null return values
instead, so the solution with the throwExceptionOnMissing-Flag was introduced. I
think we can't change this again.

About the conversion methods: As I pointed out I don't see data conversion as a
main feature of a Configuration framework. However your approach would allow to
refactor a bunch of code dealing with data conversion (especially in
PropertiesUtils) into small and flexible converter classes that can be even
customized by the user. This is very nice.

The problem I see with this is that it is surely not easy to design a functional
hierarchy of converter classes. The [convert] sandbox project has tried exactly
that and has failed so far. So if such a conversion framework existed and could
be easily embedded into Configuration, I would give it a go. But I don't want to
develop one in the Configuration project.
