JSONObject的fromObject抛出异常，在那个地方捕捉

Question

  public static JSONObject fromObject(Object object, JsonConfig jsonConfig)
    {
        if(object == null || JSONUtils.isNull(object))
            return new JSONObject(true);
        if(object instanceof Enum)
            throw new JSONException("'object' is an Enum. Use JSONArray instead");
        if((object instanceof Annotation) || object != null && object.getClass().isAnnotation())
            throw new JSONException("'object' is an Annotation.");
        if(object instanceof JSONObject)
            return _fromJSONObject((JSONObject)object, jsonConfig);
        if(object instanceof DynaBean)
            return _fromDynaBean((DynaBean)object, jsonConfig);
        if(object instanceof JSONTokener)
            return _fromJSONTokener((JSONTokener)object, jsonConfig);
        if(object instanceof JSONString)
            return _fromJSONString((JSONString)object, jsonConfig);
        if(object instanceof Map)
            return _fromMap((Map)object, jsonConfig);
        if(object instanceof String)
            return _fromString((String)object, jsonConfig);
        if(JSONUtils.isNumber(object) || JSONUtils.isBoolean(object) || JSONUtils.isString(object))
            return new JSONObject();
        if(JSONUtils.isArray(object))
            throw new JSONException("'object' is an array. Use JSONArray instead");
        else
            return _fromBean(object, jsonConfig);
    }

很好奇，问什么JSONObject的fromObject抛出异常，没有捕捉？

try{}catch(Exception e){} 把 if语句包裹起来
