New Exception with CR1 preventing a full shutdown

[Ian Swett]

I get the following exception at a point during startup.  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.  

I am running two Netty servers in the same JVM.  When I only run one, this exception still occurs, but the JVM shuts down cleanly.

This is on MacOSX 10.5.7 with JDK 1.5.
