flowable中反序列化流程变量失败Couldn't deserialize object in variable 'xxxx'

devops自动化项目中使用flowable（类似于源扮activiti的流程引擎）来进行自动化流程编排，需要将每个步骤执行的结果使用流程变量来保存，由于数据类型未知，采用fastjson来保存对象变量，使用flowable的api进行变量存储：

MapString, Object rootNodeMap = new HashMap();

String responseNode = "response";

String requestNode = "request";

// 省略resultMap处理

// 省略resultMap处理

rootNodeMap.put(responseNode, resultMap);

rootNodeMap.put(requestNode, requestMap);

runtimeService.setVariable(processInstanceId, "rootNode", rootNodeMap);

由于流程变量中包含有对象嵌套数组的情况，在使用fastjson的JSONObject保存了主节点以后，在后续使用rootNode变量时，会出现反序列化失败的情况。具体错误堆栈如下：

看字面意思理解，应该是无法识别关键字[B，猜测应该是fastjson在序列化的时候写入class的数据类型，看起来像是Byte数组之类，目前使用的fastjson版本是1.2.49版本，在github搜索了一下，目前最新版本已经到1.2.76，并且中间有一些issue提到Array、Map等，和我的应用场景比较相似，这些issue已经进行了升级解决。

于是尝试着将fastjson版本升级到1.2.76，再次执行，成功通过，问题解决。

这个问题排查定位从上周五的晚上一直到本周一的早上，持续时间很长，但是修改方式却非常简单，只是升级了fastjson的版本而已，之前一直没有怀疑是fastjson的问题，而是将重点放在自己的中间数据处理上面。所以后续遇到类似问题，可以先尝试这种快捷的方案，节约时间。
