java.util.Collections.rotate(List,int) incorrectly raises ArithmeticException
with an empty list.

Here is the example:

------t.java-----
import java.util.*;

public class t {
    public static void main(String[] args){
        Vector v = new Vector();
        Collections.rotate(v,1);
    }
}

----output:----

Exception in thread "main" java.lang.ArithmeticException: / by zero
        at java.util.Collections.rotate1(Collections.java:719)
        at java.util.Collections.rotate(Collections.java:712)
        at t.main(t.java:6)
