Imho this is an issue of the quartz scheduler. I filed a bug https://jira.terracotta.org/jira/browse/QTZ-192. As a workaround the sleep() solution suggested by Colin Peters works for me. To not trigger the shutdown twice one could also add the sleep to Spring's SchedulerFactoryBean:

import org.quartz.SchedulerException;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

public class SchedulerFactoryBeanWithShutdownDelay extends SchedulerFactoryBean{

  @Override
  public void destroy() throws SchedulerException {
    super.destroy();
    // TODO: Ugly workaround for https://jira.terracotta.org/jira/browse/QTZ-192
    try {
      Thread.sleep( 1000 );
    } catch( InterruptedException e ) {
      throw new RuntimeException( e );
    }
  }
}
