Hi,

To give some background: the idea was to let integration frameworks decide which executables should be validated to allow for consistency with their own rules for interceptor enablement and request processing; e.g. JAX-RS validates getter-style resource methods by default, or a DI framework might have its own annotation for controlling validation or descriptor format for registering interceptors.

Based on that, @ValidateOnExecution (and the settings in XML) is provided as the *recommended* way of controlling executable validation but its not obligatory: "This section expresses the behavior that integration with interception frameworks should follow. Any deviation should be considered with care as it will surprise Bean Validation users."

That being said, I agree that adding a facility for retrieving these settings via the BV API makes sense to make life easier for those integrators wishing to adhere to the BV behavior; integrators with deriving behavior could still use this API as input for their evaluation.

I will let Hardy and Gunnar answer that one, this has been discussed a lot and some arguments they provided lead to delegate the rules implementations to the integration framework.
