Sponsoring getting 5015163 "(str) String merge/join that is the inverse of String.split()" into JDK 7

[Ulf Zibis]

It works fine too.
Is coded:

public class MyClass1 {
    private final int value;

    public MyClass1(int value) {
        this.value = value;
    }

    public static int hashCode(Object key) {
        return 3;
    }

//    public static int hashCode(MyClass1 obj) {
//        return 3 * obj.value;
//    }

    public static void main(String... args) {
        MyClass1 c = new MyClass1(99);
        System.out.println(c.hashCode());
        System.out.println(hashCode(c));
        System.out.println(Object.hashCode(c)); // compile error if 
using official version of class Object
    }
}
