[seam-dev] Javassist limitation?

[Dan Allen]

While researching the internals of Seam, I observed that interceptors
are not applied to methods that a component invokes on itself, even if
those are public. This would be any method that could be written
prefixed with "this." or "super.". This behavior differs from how
interceptors work on true proxies, of which session beans are an
example.

((MyComponent) Component.getInstance(MyComponent.class)).outerMethodCall();
// intercepted

@Name("myComponent")
public class MyComponent {
  public void outerMethodCall() {
    innerMethodCall(); // not intercepted
  }
  public void innerMethodCall() { }
}

Is this something we should try to fix or should we just document it
as expected behavior? Unfortunately, I find it quite limiting because
it takes away from the fine-grained control you would get when working
with things like transactions and security.
