Simple Spring <remember-me/> ... help please

Question

All I want, is a simple remember-me. I read http://static.springsource.org/spring-security/site/docs/3.0.x/reference/remember-me.html

What I have done so far:

1. Created my own UserDetailsService to work with Hibernate / JPA. My impl. does not consider any remember-me stuff
2. Considered configuration through appContext <security:remember-me key="89dqj219dn910lsAc12" user-service-ref="jpaUserDetailsService" token-validity-seconds="864000"/>
3. Checked, that the cookie SPRING_SECURITY_REMEMBER_ME_COOKIE is really set
4. Logged in to the secured site and it works

5. When I restart my browser, I keep getting an error:

   *org.springframework.security.access.AccessDeniedException: Access is denied Authentication object as a String: org.springframework.security.authentication.RememberMeAuthenticationToken@9ab72a70: Principal: de.myapp.businessobjects.AppUser@61f68b18: Username: myad; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; PersonalInformation: 65537; ; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@957e: RemoteIpAddress: 127.0.0.1; SessionId: null; Granted Authorities: ROLE_ADMIN, ROLE_USER*

And here is my secContext.xml:

and finally some debug trace

I really don't know where to continue debugging. What have I missed? Do I have to create my own implementation of remember-me?

I would really appreciate a working sample application that demonstrates the default implementation of springs remember-me...

-------- EDIT -----------

I have just compiled and run the remember-me reference app by springsecurity itself: the spring-security\samples\tutorial account app AND the contact app. Actually, I have exactly the same problem?!?. I have tried firefox, opera and ie ... I am shattered ...
