- base class method wins against a (default) interface method, so an abstract base class method should always be implemented in a derived class; - interface methods clash regardless of abstract/default with possibly undefined behavior at run-time, so a class or interface should always define its own method for methods inherited from multiple interfaces and not from base class; - meaningful diagnostics for class inheriting conflicting JVM signatures. Since no override will happen under Java 8 rules, ACCIDENTAL_OVERRIDE is misleading for this case; - update testData.
