Java 我在使用testng部署TestActiviti时遇到了一些大问题

我使用testng测试activiti 5.19的并发性。 首先，我编写一个单元测试来部署我的bpm文件。java代码如下所示：

@ContextConfiguration(value = { "classpath:springTypicalUsageTest-context.xml" })
    public class TaskTestPerformance extends AbstractTestNGSpringContextTests{
    private static final Logger log =  LoggerFactory.getLogger(TaskTestPerformance.class);
    @Autowired
    private ItsProcessInstanceImp itsProcessInstanceService;
    @Autowired
    private ItsDeploymentImp itsDeploymentService;
    @Autowired
    private ItsProcessDefinitionImp itsProcessDefinitionService;
    @Autowired
    private ItsTaskImp itsTaskService;

    private static String bpmfile = "com/jsits/bpm/activiti/test/task/taskTest.bpmn";
    private static String deploymentname = "taskTasks";

    @Test(invocationCount=20,threadPoolSize=10,invocationTimeOut=60000)
    public void testTaskId(){
        Deployment deployment = itsDeploymentService.deploy(deploymentname, bpmfile);
        log.info(deployment.getId());
    }

}

注意：此方法将执行20次，10个线程，60秒后超时，如上面代码所示：

 (invocationCount=20,threadPoolSize=10,invocationTimeOut=60000)

我使用testNG runner运行单元测试，结果是：

===============================================

Default test

Tests run: 20, Failures: 13, Skips: 0

===============================================

错误详细信息如下：

所有这些错误

我将数据库形式

mysql

更改为

h2

，并将

invocationCount

从100更改为20，

threadPoolSize

从10更改为100，错误不会更改

但是如果我修改

threadPoolSize

=1，错误就消失了

这是否意味着activiti部署bpm，并发性不好

谢谢大家

itsDeploymentService是我的服务，它扩展了repositoryService，一分钟前，我在测试用例中使用activiti的repositoryService替换了我的itsDeploymentService，结果是一样的，没有任何变化！
