Hi Ian,
I've just checked in the fix at revision 1493. Could you confirm that
my fix works for you?
And here's the related JIRA issue:
* https://jira.jboss.org/jira/browse/NETTY-182
Thanks!

The program runs properly after this exception, but when I got to shutdown, there are threads which don't get shutdown, so the JVM doesn't exit. Sometimes I do not get this exception, and then everything goes smoothly. I verified that when I switch back to Beta3, this problem never occurs.
