null

Hi,

I'm using JSON to deserialize an input string that contains a null value for certain hashmap property. Does anyone have any clue why this exception occurs ? Is it possible that null is not accepted as a value Is this configurable somehow ?

input sample:

{"prop1":"val1", "prop2":123, "prop3":null}

stacktrace:

net.sf.json.JSONException: null object
    at net.sf.json.JSONObject.verifyIsNull(JSONObject.java:2856)
    at net.sf.json.JSONObject.isEmpty(JSONObject.java:2212)

Thanks.
