vaadin. A lot of warnings: Failed to define class ... from Service Module Loader

vaadin 6.8.13

My application works normally. But during application work vaadin is showing a lot of warnings in console.

Is there any possibility to disable this warnings without adding gwt library? Example of warning:

16:09:27,342 WARN  [org.jboss.modules] (http-localhost-127.0.0.1-8080-1) Failed to define class com.vaadin.terminal.gwt.client.ui.ShortcutActionHandler$ShortcutActionHandlerOwner in Module "deployment.vaadin_1.war:main" from Service Module Loader: java.lang.LinkageError: Failed to link com/vaadin/terminal/gwt/client/ui/ShortcutActionHandler$ShortcutActionHandlerOwner (Module "deployment.vaadin_1.war:main" from Service Module Loader)

Try this

This error will happen when we use JBOSS AS - https://developer.jboss.org/thread/169575?tstart=0

Reason: Some or all classes in gwt-user.jar required for compiling the Vaadin client side widgets are loaded by the JBoss AS unnecessarily.

Fix: Include gwt-user.jar to the deployment package in WEB-INF/lib folder with the vaadin.jar.

References - Deploy vaadin to JBoss 7.0 gives me a ClassNotFoundException
