..
Broken both on annotation and XML validators. Empty messages worked 2.0 but not
in 2.1 (Tested up to 2.1.6).
This is annoying on ModelDriven actions, since you can't delegate validations
to model object. (empty message crashes validation and non-empty message will
be appended to the actual messages of models validators).
