Apologies if this is a FAQ, but I tried for some time to find it and 
couldn't.

If I have a bean with a Long or Number property, e.g.

class TestBean {
   private Long number = null;

   public Long getNumber() { return number; }
   public void setNumber(Long number) { this.number = number; }
}

and serialize an instance where the "number" property is null,  for 
example using

JSONSerializer.toJSON(new TestBean()).toString()

it gives the result

{"number":0}

and deserializing this gives an instance that is not equal to the original.

Is this expected or a bug?

I was expecting a serialized form of

{"number":null}

which, when deserialized does give me an instance equal to the original.
