[classlib][util] unexpected ClassCastException for Collections.binarySearch(..)
-------------------------------------------------------------------------------

                 Key: HARMONY-1367
                 URL: http://issues.apache.org/jira/browse/HARMONY-1367
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov


The method java.util.Collections.binarySearch(..) throws ClassCastException on Harmony while
works OK on RI.

==================== test.java ==================
import java.awt.HeadlessException;
import java.util.*;

public class test {
    public static void main(String args[]) {
        List localList = new LinkedList();
        try {
            Collections.binarySearch(localList, new HeadlessException());
            System.out.println("OK: no exception expected!");
        } catch (Exception e) {
            System.out.println("unexpected exception: " + e);
        }
        localList.add(new String());
        try {
            Collections.binarySearch(localList, new HeadlessException());
            System.out.println("Exception expected!");
        } catch (Exception e) {
            System.out.println("OK: " + e);
        }
    }
}
