integTests for multi-project Spring app constructing an ApplicationContext per project

I work on a Spring multi-project app whose ApplicationContext takes some time to start-up. It seems that each sub-project’s integTest task creates it’s own ApplicationContext, which results in the build taking quite some time. Are others seeing this ApplicationContext per sub-project behavior (or are we doing something silly to bring this on ourselves)? If so, are there any suggestions for how to get one applicationContext for the entire multi-project build?

Thanks in advance.
