Re: [aspectj-users] introductions and inheritance

Hi Robert. 

I have just run through your initial
test case description using the latest development build (details in Adrian's
previous note to the list) and the original problem does not appear to
occur anymore. If possible, can you confirm that an upgrade fixes things
for you ?

Best regards,
George

could be indeed the same bug. but it seems a bit more serious cause
it happens with the ajc too.

i tried the following workaroud (to no avail thou)
public aspect Implementor{

   public interface IFoo_A extends IFoo;
   public interface IFoo_B extends IFoo;

   declare parents: BaseBar implements IFoo_A;
   declare parents: DefaultBar implements IFoo_B;}

i guess the only solution would be to do the implementation
code into IFoo_A and IFoo_B instead of IFoo. which would of
coursse would be code duplication. and we dont want that, or do we?
naaah!

ciao robertj
