Why GXT exception occurs and how to fix it?

I am trying to create some simple GWT+GXT application.

I've created simple class MySampleApplication.java:

public class MySampleApplication implements EntryPoint {
    public void onModuleLoad() {
        AlertMessageBox d = new AlertMessageBox("title", "message");
        d.show();
    }
}

and simple declaration MySampleApplication.gwt.xml:

<inherits name='com.google.gwt.user.User'/>
<inherits name='com.sencha.gxt.ui.GXT'/>
<inherits name='com.google.gwt.user.theme.clean.Clean'/>
<stylesheet src="reset.css" />
<entry-point class='com.mySampleApplication.client.MySampleApplication'/>

It looks like there is nothing easier, but it fails:

onModuleLoad() threw an exception
Exception while loading module com.mySampleApplication.client.MySampleApplication.
See Development Mode for details.

Remove <inherits name='com.google.gwt.user.theme.clean.Clean'/> it's not supported by GXT, see Getting Started
