Well, it failed on travis; see build # 10 here: https://travis-ci.org/spring-projects/spring-integration/pull_requests

As you can see, it took me a lot of attempts to get this PR to build successfully and this change made it successful.

I fear that travis is going to expose more of our subtle test timing issues than Bamboo does :frowning: 

I will try adding your commit to the PR to see how travis likes it, but I am not confident.
