According to the javadoc (for java.util.Map.putAll(Map t)), java.util.jar.Attributes.putAll(Map
attr) should throw ClassCastException if "if the class of a key or value in the specified
map prevents it from being stored in this map." Key class in the Attributes Map is
Attributes.Name, so any other object can not be put as a key and ClassCastException should be
thrown in such a case. However, ClassCastException is not thrown in such a case in JDK 1.2-fcs.
See also Bug Id: 4199913.

According to the javadoc (for java.util.Map.putAll(Map t)), java.util.jar.Attributes.putAll(Map
attr) should throw NullPointerException if "this map does not permit null keys or values, and the
specified key or value is null." Null keys should not be permitted for Attribute names (see Bug Id:
4199920). This means that putAll(Map attr) should throw NullPointerException if attr contains null
keys. Currently putAll(Map attr) does not throw NullPointerException if attr contains null keys in
JDK 1.2-fcs.

A test example which demonstrates this problem.
===== Test21.java ========
import java.util.jar.Attributes;
import java.util.HashMap;

public class Test21 {

    public static void main (String argv[]) {
        Attributes attr = new Attributes();
        HashMap hm = new HashMap();
    
        hm.put("NewName", "NewValue");
        try { attr.putAll(hm);
            System.out.println("Failed: ClassCastException expected");
            return;
        } catch (ClassCastException cce) { //OKAY
        }
    
        hm.clear();
        hm.put(null, null);
        try { attr.putAll(hm);
            System.out.println("Failed: NullPointerException expected");
            return;
        } catch (NullPointerException npe) { //OKAY
        }

        System.out.println("Passed");
        return;
    }
}
