Gunnar Morling commented on HV-575:
-----------------------------------
Ah, I think you're applying the annotation processor to a project which hasn't the Bean Validation API (validation-api-1.0.0.GA.jar) as dependency. Then the registration of supported types for built-in constraints ({{@Size}} etc.) fails (the AP hasn't the API itself as dependeny anymore due to HV-457).
I guess we could simply log a WARN message in this case and stop the AP from any further processing. Does the AP work when you add Hibernate Validator (and thus transitively the BV API) as project dependency?
