Activiti OSGI 和蓝图的问题

Question

我尝试在 KARAF OSGI 中使用 Activiti 和骆驼。

我从服务组合配置中复制了一些部分。

        <to uri="jobsbpmn://bpmn"/>
    </route>
</camelContext>

我可以在容器中毫无问题地部署捆绑包。当我使用骆驼模块触发工作流时，我得到了这些异常：

2016-11-08 11:56:43,569 |错误 | m://client_queue | JobsBpmnProducer | 45 - 工作记录 - 1.0.0 |没有找到与此相关的 Processdefinition 标识符 ActivitiException：期望一个 Activiti Camel 模块的 SpringProcessEngineConfiguration。
类转换异常： org.activiti.engine.impl.cfg.JtaProcessEngineConfiguration 不能 转换为 org.activiti.spring.SpringProcessEngineConfiguration**

如何使用 Spring 部署符合 OSGI 的 Processengine 以使 Camel 工作？

这个问题可能已经在活动代码中得到修复。 见https://github.com/Activiti/Activiti/pull/519

你可以试试最新的 Activitiy 版本吗？
