Competing Consumers fails for jms queue using AdviceWith

I was trying to test two routes that start from the same endpoint. The endpoint is a jms queue, so it should be able to have multiple consumers attach to it. When I use the standard CamelTestSupport methodology and let it create and start my context, mock my out points, etc. everything passes (see CompetingConsumersWorks.java). However when I try and use the strategy of not letting the junit support create everything, ie.
public boolean isUseRouteBuilder()

public boolean isUseAdviceWith()

and try and use AdviceWithRouteBuilder to mock out routes the test doesn't pass (see CompetingConsumersDoesNotWork.java). I can actually get it to work, but only if I start the context before adding the second set of routes to the context (see comments in code).
