Web application context scope strange behavior

Question

Using spring on a webservice I have this code:

@RequestMapping(value = "/testOperation", method = GET)     
public String testOperation() throws Exception 
{                   
    ts.setName("First Value");
    ts.name = "Second Value";
    return ts.getName() + " and " + ts.name;                
}

The response received is "First Value and Second Value". I do not understand why is not "Second Value and Second Value". ts is a request scope injected variable. The code is:

@Component
@Scope(value=WebApplicationContext.SCOPE_REQUEST, proxyMode=ScopedProxyMode.TARGET_CLASS)
public class TS implements Serializable{        
    public String name;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

I do not understand this behavior

As TS is configured to be request scoped obviously spring creates proxy for it. So setName and getName invocations are redirected to TS instance that is created for every request. But direct field reference can't be proxied and it affects only instance injected to controller.
