How to wait for process to reach a user task

We have a use case where we're starting an Activiti process within a web app; the actual process that we start might vary depending on what the user has done within our app prior to that point. After starting the process, we want to allow it to proceed until it reaches a user task, and then we want

This is the default behavior:

Thanks for the reply. We had added some console logging that included the thread id, and realized that the service task (the process only has one initial service task) was operating in the main thread, and was completing up to the first user task, at which time the thread returned to the caller. But we checked our service task and it's definitely not asynchronous. The problem is intermittent and that's why we thought it was a race condition. We'll dig a little deeper. Thanks again for confirming the default behavior.
