Timeout annotation doesn't work on protected method

According to ejb3 spec:
------- ejb-3_0-fr-spec-ejbcore.pdf 18.2 (p. 484) ------------
A Timeout method can have public, private, protected, or package level access. A Timeout method must not be
declared as final or static.
---------------------------------------------------------------------------

But when I declare timeoutHandler in ExampleTimerBean as protected JBoss throws an exception:
11:39:18,271 ERROR [TimerImpl] Error invoking ejbTimeout: javax.ejb.EJBException: No method has been annotated with @Timeout

So, a testcase can be:
---------------------------------------------------------------------------
package org.jboss.tutorial.timer.bean;

import java.util.Date;
import javax.annotation.Resource;
import javax.ejb.Remote;
import javax.ejb.SessionContext;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
import javax.ejb.Timer;

@Stateless
@Remote(ExampleTimer.class)
public class ExampleTimerBean implements ExampleTimer
{
private @Resource SessionContext ctx;

public void scheduleTimer(long milliseconds)

{ ctx.getTimerService().createTimer(new Date(new Date().getTime() + milliseconds), "Hello World"); }

@Timeout
protected void timeoutHandler(Timer timer)

{ System.out.println("---------------------"); System.out.println("* Received Timer event: " + timer.getInfo()); System.out.println("---------------------"); timer.cancel(); }

}
