Trying to upgrade from 3.0.11 to 3.2.0 and get this error...

So I'm trying to upgrade to 3.2 from 3.0.11, but I get and error about webSocketMessageBrokerStats which ends up being Caused by: java.lang.IllegalStateException: ThreadPoolTaskExecutor not initialized. Any Ideas what could be causing this or a possible workaround?

After a lot of debugging I finally stumbled on the Issue the WebSocketConfig had an @Configuration annotation, that combined with the component scan and the reference from resources.groovy, caused weird things to happen. This is the second time during this upgrade I've looked at the code, and wondered how it ever worked in the first place.
