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
