Error forcing a timer event in a test case

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I'm trying to write an automated test case to simulate the behavior of some timers that are in my process diagram.  However, whenever I call managementService.executeJob(), I get an "already taking a transition" exception.  Is there something else that I need to do?  I'm currently using Activiti 5.11.  The process instance that I'm starting starts a single timer which escalates if no action is taken for one hour.

@Test
@Deployment
public void myTimerTestExample() {

    //Start a new process instance
    String processDefinitionKey = "mykey";
    ProcessInstance instance = runtimeService.startProcessInstanceByKey(processDefinitionKey);
    String processInstanceId = instance.getProcessInstanceId();

    //Find the timer job.  For this process, there is exactly one timer job which is always started
    Job timerJob = managementService.createJobQuery().processInstanceId(processInstanceId).singleResult();
    Assert.assertNotNull(timerJob );

    //Force the timer to fire
    managementService.executeJob(timerJob .getId());

    //TODO: Validate the results of the timer executing
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I get the following exception when calling managementService.executeJob():

2013-01-28 18:18:39 ERROR org.activiti.engine.impl.jobexecutor.TimerCatchIntermediateEventJobHandler exception during timer execution
org.activiti.engine.impl.pvm.PvmException: already taking a transition
