In case this helps someone else, I found a solution to this problem.  By creating a Spring ApplicationListener that listens to the shutdown event, you can signal the jBPM job executor to shut down when the context is stopped.

@Component
@SuppressWarnings("unchecked")
public class SpringJbpmJobExecutorShutdownHook implements ApplicationListener {
    
    //~~ Static Fields/Initializers ==========================
    
    static final Logger log = Logger.getLogger(SpringJbpmJobExecutorShutdownHook.class);
    
    //~~ Dependencies ========================================
    
    @Resource
    ProcessEngine processEngine;
    
    //~~ Methods =============================================
    
    public void onApplicationEvent(ApplicationEvent event) {
        if (event instanceof ContextClosedEvent ) {
            log.info("Spring ApplicationContext shutting down.  Closing jBPM process engine.");
            processEngine.close();
            log.info("jBPM process engine closed.");
        }
    }
}
