使用并行和排他网关组合的时候会卡在running状态

[FJiayang]

问题描述

流程配置如图

ProcessInstance启动后，检查流程状态，发现卡在join Gateway位置，是什么原因呢？

环境：

• springboot 3.3.4
• jdk 17
• smartengine 3.0.0

    @Test
    public void parallel() throws Exception{
        PersisterSession.create();
        RepositoryCommandService repositoryCommandService = smartEngine.getRepositoryCommandService();
        ProcessDefinition processDefinition = repositoryCommandService
                .deploy("smart-engine/deploy.bpmn").getFirstProcessDefinition();
        Map<String, Object> request = new HashMap<>();
        request.put("deploy3", "true");
        ProcessCommandService processCommandService = smartEngine.getProcessCommandService();
        ProcessInstance instance = processCommandService.start(processDefinition.getId(), processDefinition.getVersion(), request);
        List<ExecutionInstance> executionInstances = itsTradePipelineService.query(instance.getInstanceId());
        for (ExecutionInstance executionInstance : executionInstances) {
            log.info("executionInstance:{}", executionInstance);
        }
        PersisterSession.destroySession();
    }

输出

2024-10-16T17:37:45.814+08:00  INFO 20039 --- [springboot-smartengine] [pool-2-thread-2] t.f.s.s.task.Deploy2Task                 : Deploy2Task

预期输出应该所有任务都是完成状态

排查过程

移除排他网关运行正常

当移除排他网关后，流程正常结束

输出如下

移除排他网关后运行多次偶发卡死在join gateway

    @Test
    @RepeatedTest(10)
    public void parallel() throws Exception{
        PersisterSession.create();
        ...
        PersisterSession.destroySession();
    }

移除排他网关后，重复运行10次单测，除了第1、2次正常结束，后续8次都会卡在join gateway，输出如下
