[interceptors-spec users] Re: [jsr345-experts] Interceptors 1.2 MR candidate is available for the final review

Marina, something that is not clear to me. Let's say you have an
interceptor class that intercept construtor and method invocations,
something like :

public class LoggingInterceptor {

  *_at_AroundConstruct*
  private void logConstructor(InvocationContext ic) throws Exception {...}

  *_at_AroundInvoke*
  public Object logMethod(InvocationContext ic) throws Exception {...}
}


If the bean defines the interceptor on the class, all interceptions
(contructor + method calls) will happen, correct :

*_at_Interceptors(LoggingInterceptor.class)*
public class CustomerService {
  public void createCustomer(Customer customer) {...}
  public Customer findCustomerById(Long id) {...}
}

But if the interceptor is defined only on a method, the @AroundConstruct
will not be invoked. Am I correct here ? By reading the spec this sounds a
bit vague (or I might have missed something)

public class CustomerService {
  public void createCustomer(Customer customer) {...}
* @Interceptors(LoggingInterceptor.class)*
  public Customer findCustomerById(Long id) {...}
}


Thanks
Antonio
