The javadoc for java.util.Arrays.fill(Object[], Object) and
java.util.Arrays.fill(Object[], int, int, Object) says nothing about situation
when array contains objects that are not comparable with key value.

In fact ArrayStoreException is thrown (jdk1.2.2).

Here is example demonstrating this behaviour
------------- Test1.java --------------

import java.lang.Integer;
import java.lang.String;
import java.util.Arrays;

public class Test1 {
    public static void main(String[] argv) {
        String a[] = {"test1", "test2", "test3"};
        Integer val = new Integer(0);
        try {
            Arrays.fill(a, val);
        } catch (ArrayStoreException e) {
            System.out.println("WARNING! Undocumented exception"
                               + " has been thrown");
            return;
        } catch (Exception e) {
            System.out.println("ERROR! Illegal exception has been thrown");
            return;
        }
        System.out.println("ERROR! No exception has been thrown");
        return;
    }
}

------------- output --------------
<kai@moon(pts/8).275> java Test1
WARNING! Undocumented exception has been thrown
