The compiler should not compile related methods with different signatures but
same erasures. Eclipse compiles the example below without errors and prints
"InvertedPair#setA(1.1)" when run.

Javac says: "name clash: setA(A) in InvertedPair<A,B> and setA(A) in Pair<B,A>
have the same erasure, yet neither overrides the other"

public class P {
    public static void main(String[] args) {
        Pair<Double, Integer> p= new InvertedPair<Integer, Double>();
        p.setA(new Double(1.1));
    }
}

class Pair<A, B> {
    public void setA(A a) {
        System.out.println("Pair#setA(" + a + ")");
    }
}

class InvertedPair<A, B> extends Pair<B, A> {
    public void setA(A a) {
        System.out.println("InvertedPair#setA(" + a + ")");
    }
}
