vaadin 6.8.13

我的应用程序正常运行。但在应用程序工作期间，vaadin在控制台中显示了很多警告。

是否有可能在不添加gwt库的情况下禁用此警告？警告示例：

试试这个

当我们使用JBOSS AS - https://developer.jboss.org/thread/169575?tstart=0

时会发生此错误

原因：编译Vaadin客户端小部件所需的gwt-user.jar中的部分或全部类都是由JBoss AS不必要地加载的。

修复：使用vaadin.jar将gwt-user.jar包含在WEB-INF / lib文件夹中的部署包中。

vaadin。很多警告：无法从服务模块加载器定义类....
