HashedWheelTimer not executing scheduled tasks

[esnjonas]

Hi,
First of all, big thanks to Trustin Lee and the rest of the Netty
communnity.

And now to the problem :)
We're using Netty 3.2.4-Final and we are experiencing problems with the
HashedWheelTimer. 
It simply skips executing a scheduled task if the task is scheduled again
from within the run-method of the TimerTask.

I've identified the the time spent inside the run method affects this
scenario. This simple test below fails on both Linux and Windows.

import org.jboss.netty.util.HashedWheelTimer;
import org.jboss.netty.util.Timeout;
import org.jboss.netty.util.TimerTask;
import org.junit.Test;

import java.util.concurrent.TimeUnit;
import java.util.concurrent.atomic.AtomicInteger;

import static org.junit.Assert.assertTrue;

public class HashedWheelTimerTest
{
    private static class TestTimeout implements TimerTask
    {
        protected final AtomicInteger execCount = new AtomicInteger(0);

        public void run(Timeout timeout) throws Exception
        {
            Thread.sleep(1000);

            execCount.incrementAndGet();
            timeout.getTimer().newTimeout(this, 100, TimeUnit.MILLISECONDS);
        }
    }

    @Test
    public void testExpire() throws InterruptedException
    {
        HashedWheelTimer wheelTimer = new HashedWheelTimer(100,
TimeUnit.MILLISECONDS);

        wheelTimer.start();

        TestTimeout tt = new TestTimeout();

        wheelTimer.newTimeout(tt, 100, TimeUnit.MILLISECONDS);

        Thread.sleep(5000);

        wheelTimer.stop();

        assertTrue(tt.execCount.get() > 1);

    }
}
