So, a quick explanation for this is that, recent changes made the
runtime behavior different. If you are doing getService("ABC"), you
need to make sure that the target component has only one service,
otherwise you should use getService("ABC/ServiceName"). Please see if
this helps in your case.
In my case, i had a bug where the composite wasn't finding the
components, and I was getting the same error message...
