How can I avoid the warning in this scenario? [message #1436855]

public class A {
    // warning occurs on this method:
    // The method foo() from the type A can potentially be declared as static
    protected boolean foo() {
        return false;
    }
}

public final class B extends A {
    @Override
    protected boolean foo() {
        // do non-static, B specific things
        return true;
    }
}

Is this behavior expected? It seems like a spurious warning to me. I wonder if it warrants filing a bug report.

I understand your question. When we are in A, we see that foo is not calling any other function of A. So let us narrow down it's scope. Make the method static and thus the method can only call static methods.

There is no way one can figure out while processing A that what are subclasses of A. That is why we have the word "potentially" Smile
