Spring Security instance class - spring

Question

When I create some class like below
#Controller
public class MYTokenEndpoint extends AbstractEndpoint {
public MYTokenEndpoint(){
System.out.println("A");
}
#RequestMapping(value = "/oauth/itop_token")
its constructor is called with this log
org.springframework.beans.factory.support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory#198d9cf: defining beans
and after constructor called it's called again with this log
org.springframework.security.access.method.DelegatingMethodSecurityMetadataSource - Adding security method
what's happend there ?
thanks

When aspects are applied using CGLIB proxies, constructor of the class being proxied is called twice, it's a normal behaviour, see 7.6 Proxying mechanisms.
