Hi again,
It took some time, but finally I could manage to test one of the suggested workarrounds.
EJBs in our application are automatically generated, so I can't easily rename the jar files, but I could manage to customize our code generator to use the 'mappedName' attribute.
Unfortunately it still fails, but this time with another exception:

I have tested the application in 4.3 and it works.
An example of how the EJB declaration looks like:
| @Stateless(name="UserProfileService")
| public class UserProfileServiceBean extends FndImplementationBean implements UserProfileServiceLocal { ...
|
And how we refer to the same EJB; the original code:
| @EJB private UserProfileServiceLocal userProfileService;
|
and now, after introducing the 'mappedName' attribute:
| @EJB(mappedName="ifsapp/UserProfileService/local") private UserProfileServiceLocal userProfileService;
