hi hardy,

thx for moving it to an own thread!

a copy of my last answer:

...
it's just about:
 - an interface which directly allows simple but still flexible custom implementations of (custom) message-sources (including a simple delegation to a ResourceBundle) - see [1].
vs.
 - an interface which is restricted to ResourceBundle. -> if it isn't possible to use ListResourceBundle or PropertyResourceBundle, users have to implement #getKeys which might not be possible (/ that easy) for some advanced use-cases.

the rest is more or less the same - if the MessageInterpolator receives a key, it uses the new interface for the lookup (if there is no custom implementation of the new interface or no result for the given key, the existing default bundle (ValidationMessages) is used as a fallback).

regards,
gerhard

AFAIU Gerhard proposes a more general interface which is independent from ResourceBundles. Underneath you still can use them, in fact you would have to for
ValidationMessages.properties. We would have to to define the MessageResolver interface and then also define that the default implementation of this interface
resolves against ValidationMessages.properties. Even with the ResourceBundleLocator interface you need to somehow specify that a default implementation exists
which uses ValidationMessages.properties. Is this what you have in mind Gerhard?

+1 That would be the best.

Right. For that reason using ResourceBundleLocator still feels a little more "natural" to me.
