public @interface CallbackRolesAllowed
Specifies the list of roles permitted to access callback method(s) in an application.
The value of the CallbackRolesAllowed annotation is a list of security role names.
This annotation can be specified on a stub or on callback method(s).
Specifying it at a stub level means that it applies to all the callback methods
belonging to this stub.
Specifying it on a callback method means that it is applicable to that method only.
If applied at both the stub and methods level , the method value overrides the stub value
if the two conflict.
