NullPointerException

[yangru...@gmail.com]

When an argument of some function is null, it will throw TypeError not NullPointerException.

public void test(){

    try{

          Boolean.TRUE.compareTo(null);

         } catch(NullPointerException){

                  System.out.println("NPE");

         }

}

It will output TypeError:Unable to get value of the property "valueOf": object is null or undefined

I think this error can be easy fixed. Boolean.compareTo is defined at code.google.com/p/java2script/source/browse/trunk/sources/net.sf.j2s.java.core/src/java/lang/Boolean.js#76

I would fixed it to be :

Clazz.overrideMethod (Boolean, "compareTo",
function (b) {
if(b==null)throw new NullPointerException();
return (b.value == this.valueOf () ? 0 : (this.valueOf () ? 1 : -1));
}, "Boolean");


But I won't since I'm not sure how can this impact... Renjian ?
