java version "1.4.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta2-b77)

 import java.util.*;

 public class HM
 {
    public static void main(String[] argv)
    {
        Map map = new WeakHashMap(0);
        map.put("a","b");
    }
 }

 This runs fine in java 1.3, but throws an illegalArgumentException on the
 constructor in 1.4. This is undocumented, inconsistent with HashMap and
 probably erroneous.
