This issue seems to be a TP. Nevertheless, it is weird that we are reporting a SUPERCLASS_REMOVED breaking change in all cases. The real cause behind this situation is a CLASS_REMOVED breaking change. Let's investigate a bit more. In any case, there is indeed an issue as reported by the broken uses, the problem is that nor JDT nor the Maven compilers report the error.
