If you are getting IllegalArgumentException, just make a few changes on client side model or bean. 如果要获取IllegalArgumentException，只需对客户端模型或bean进行一些更改。
Just mention package path when you returning the value with his data type. 当返回带有他的数据类型的值时，只需提及包路径。
public native final Boolean apply() /*-{
return this.apply ? @java.lang.Double::Boolean(D)(this.apply) : null;
}-*/;
