Separate interfaces and implementation emf ecore

Imagine the following situation: we have bundle A with interface IntA defined in emf model and bundle B with class classB. When we generate code from the emf model in the bundle A we will get IntA and IntAImpl files which contain interface declaration and implementation respectively.

Now suppose that we want that some method implementation in IntAImpl could work with class classB. We need to add bundle B to required bundles of the bundle A. We also want that classB could operate with interface IntA from bundle A. That makes us to add bundle A to the required bundles of bundle B. We've just got cyclic dependency.

Everything would have been fine if interfaces and implementation had been declared in the different bundles - say, A.int and A.impl. In this way, B and A.impl would have had dependency from A.int and A.impl would have had dependency from B - no cycle.

Now comes the question - is it possible to make emf generate interfaces and implementations in different bundles? If not then how is it supposed to deal with this kind of a problem?

There is an old post from 2008 that answers this question:

In short: it is not possible.

In any case, you state that "IntAImpl could work with class classB". So, is this a theoretic situation you have in mind that will not happen or are you sure this situation will happen?
