[jboss-user] [JBoss AOP] - Aspect scope and construction pointcuts

[chrismeadows]

AOP 1.5.2 libs being used
I'm having problems with construction pointcuts and PER_INSTANCE scope. All other scopes work as expected, but it is PER_INSTANCE that I need.


@Aspect(scope=Scope.PER_INSTANCE)
public class MyAspect {
  
  private static final Logger log = Logger.getLogger(MyAspect.class);
    
  @Bind (pointcut="construction(public MyAspected->new())")
  public Object constructorAdvice(ConstructionInvocation invocation) throws Throwable {
    Object master = invocation.invokeNext();
    log.info("Constructed Aspect");
    return master;
  }
}

--

public class MyAspected {

  private static Logger log = Logger.getLogger( MyAspected.class );
  public MyAspected() {
    log.info("Constructed");
  }
}

--

public class TestMyAspected extends TestCase {

  static {
    BasicConfigurator.configure();
  }

  public void testMyAspected() {
    MyAspected ta = new MyAspected();
  }
}


All scopes work correctly except PER_INSTANCE. With that scope, I get a nasty exception which looks like the AOP framework couldn't find the Advice for the aspected constructor.

Any ideas?
