[aspectj-users] around advice on constructors

[Daniel McAllansmith <daniel@xxxxxxxxxxxxxxxxxx>]

Hi,

I'm trying to replace all newly created instances of an interface (Iface) with 
dynamic proxies which delegate to the actual new instance.
This is pretty straight forward if I mandate that all instances must be 
created through factories with a well-known method which returns Iface 
(rather than IfaceImpl).

Ideally I would like to be able to use code like the following:

Iface if = new IfaceImpl();

and an around() which creates a Proxy implementing the classes implemented by 
the result of proceed()

unfortunately this results in a ClassCastException, the dynamic proxy is not 
an instance of IfaceImpl, only Iface.

Does anybody know of any chicanery which might allow me to do this?

Thanks
Daniel
