According to:
http://developer.java.sun.com/developer/bugParade/bugs/4637755.html for a Java
1.4 compatible javac the compiler should not allow access to protected members
from classes defined outside their package, even if members are overrider the
method from a base class that *is* in the accessor's package. This "bug" existed
in the javac included with JDK 1.3, but is "fixed" in the JDK 1.4 javac.

Included is a piece of sample code that demonstrates the problem. With Sun's
javac from JDK1.4 the following error is reported on compilation:

PackageA/MainClass.java:12: overriddenMethod() has protected access in
PackageB.DerivedClass
		derivedObject.overriddenMethod();

Eclipse's java compiler compiles the code happily, even when JDK1.4
compatibility is enabled.

I should mention that the attachment *does* compile with Eclipse, but it should
not. I've commented the line that should not compile.

Works for me in latest. This is a duplicate of bug 22428.
Fix is part of 2.1-M1 build.
