ResourceResolver and MessageSource look very redundant

[keilw]

With generic signatures in ResourceResolver, it and MessageSource feel almost identical.
It could be more efficient to have ResourceResolver< String > or at most a MessageSource (or MessageResource ;-) simply extend ResourceResolver< String > providing extra methods like asResourceBundle().

I think it's ok to call "String myMessage = source.resolveResource("dialog.title", myLocal)" instead of "String myMessage = source.getMessage("dialog.title", myLocal)" since a text/message is a resource, too.

True, they look very similar but MessageSource has a narrower contract than ResourceResolver (it does not need the Converted assisted methods). Also, ResourceResolver cannot be generified to a single type (see #6)
