FieldAccess for inherited field in subclass does not get replaced
-----------------------------------------------------------------
Key: JBAOP-346
URL: http://jira.jboss.com/jira/browse/JBAOP-346
Project: JBoss AOP
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 1.5.3.GA
Reporter: Kabir Khan
Assigned To: Kabir Khan
Fix For: 1.5.4.GA, 2.0.0.alpha3
This is a reopening of JBAOP-339 since that was closed for 1.5.3.GA. From JBAOP-339:

release 1.5.3 fixed the issues previously reported in that field level access by classes not in the class hierarchy of the aspectized class will result in the interceptor running. However if the class is in the class hierarchy of the aspectized class and it accesses the inherited field the interceptor is not run. I'm including a second test case to demonstrate... quickly though here is the basic premise
-> = inherits from
Class heirarchy
D -> C -> B -> A
A declares annotated field...
package testcase;
public abstract class A
{
/**
* This field is annotated.
* Any field access (get) should cause the interceptor to run
*/
@MyFieldAnnotation
protected String myField;
}
Main test case...
package testcase;
public class Main
{
/**
* @author gdunkle
* @param args
* TODO Implement auto-generated method stub
*/
public static void main(String[] args)
{
C cInstance = new C();
D dInstance = new D();
// this doesn't work in 1.5.3 or 1.5.2
System.out.println(cInstance.toString());
// this works in 1.5.3
System.out.println(cInstance.myField);
// this won't work even if we uncomment the field in B
// b/c it inherits from C and there is no duplicate field
System.out.println(dInstance.toString());
// this works in 1.5.3
System.out.println(dInstance.myField);
}
}
verbose output when run under 1.5.2
