Hello,
 
I don't know why #2 and #3 do not work in the following example.
Please, help me out.
 
(1) works well
<bind pointcut="field(* bank.BankAccount->*)">
 
(2) does not work.
<bind pointcut="field(@bank.SecurityFieldAnnotation bank.BankAccount->*)">
   
(3) does not work.   
<bind pointcut="field(* bank.BankAccount->@bank.SecurityFieldAnnotation)">
 
----------------------------------------------------------------------------
package bank;
import bank.SecurityFieldAnnotation;
 
public class BankAccount 
{
 @SecurityFieldAnnotation 
 private int counter;
   
   public int getCounter() { return counter; }
 public void setCounter(int counter) { this.counter = counter;}
}
----------------------------------------------------------------------------
package bank;
import java.lang.annotation.ElementType;

@Target({ElementType.FIELD})
public @interface SecurityFieldAnnotation {

   public Object access(FieldReadInvocation invocation)
       throws Throwable {
    System.out.println("[DBG] access read");
    return invocation.invokeNext();
   }
 
   public Object access(FieldWriteInvocation invocation)
       throws Throwable {
    System.out.println("[DBG] access write");
      return invocation.invokeNext();
   }
}
