Project with the classes. Error is on 

Build ID: I20090313-0100

Steps To Reproduce:

pkg1 ->Base class. Declares a protected abstract method
pkg2 ->Derived extends Base. defines the method and uses that. 

While calling the method from Derived, I get an error saying its not accessible. Further, the quick fix suggests to make the method protected in Base (which is already protected)
Comment 1 Philipe Mulet CLA 2009-03-20 06:13:30 EDT 
This is expected behavior. A protected member can only be used for receiver type (or one of its subtype). This is why implicit access is allowed, but not via an AbstractBase.


========
AbstractBase other = null;
getSomething(arg); // no error
other.getSomething(arg); // error here. Also see the quick fix

ConcreteDerived other2 = ...;
other2.getSomething(null); // allowed as well.
