部署流程或上传bpmn20.xml流程定义文件异常

一、该问题的重现步骤是什么？

1.  管理员账号登录，进入“流程部署”或者“模型管理”界面

2.  在流程部署界面上传标准bpmn20.xml文件；或在“模型管理”界面部署某个已存在的模型

3.  上传的bpmn20.xml文件是在blade提供的flowable流程编辑器中开发的，最简单的流程模板也尝试过。

二、你期待的结果是什么？实际看到的又是什么？

期待流程部署成功，但是系统抛异常

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

BladeX-Boot 2.0.3.RELEASE

四、请提供详细的错误堆栈信息，这很重要。
