GWT issue with Java method calls from JSNI

Question

I tried a google example on this page: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideJavaFromJavaScript

I want to be able to call a Java method from JSNI, but nothing happens. There are no errors, but methods are not called. However, I can change the fields from my class.

Here is the code I tried:

package com.jsni.client;
import com.google.gwt.core.client.EntryPoint;

public class Testjsnii implements EntryPoint {
      String myInstanceField;
      static int myStaticField;

      void instanceFoo(String s) {
          System.out.println(s);
      }

      static void staticFoo(String s) {
          System.out.println(s);
      }

      public native void bar(Testjsnii x, String s) /*-{

        [e-mail]::instanceFoo(Ljava/lang/String;)(s);
        [e-mail]::instanceFoo(Ljava/lang/String;)(s);
        @com.jsni.client.Testjsnii::staticFoo(Ljava/lang/String;)(s);
        var val = [e-mail]::myInstanceField;
      }-*/;

    public void onModuleLoad() {
        bar(this,"Hello");
    }
}

It does not print anything on the console, but only waring, which says:

[WARN] [testjsnii] - JSNI method '@ com.jsni.client.Testjsnii :: bar (Lcom / jsni / client / Testjsnii; Ljava / lang / String;)' returns> JavaScript object type value (1), but it was void declared it should not return value> at all

I wonder what the problem is.

Thanks for the help.
