关于JBPM的一个严重错误10

我用JBPM发生了下面的错误：
null index column for collection: org.jbpm.context.exe.TokenVariableMap.variableInstances

而且这个错误发生以后，我再发布新模板，用新模板去创建流程，在调用processInstance.getVariable方法的时候都会出这个错误，就是把模板的名字改了也不行，重新发布的模板创建新流程都会发生错误，我用JbpmContext.getGraphSession().deleteProcessDefinition(long)去删除某些以前的流程定义的时候，还出这样的错误，

现在唯一的解决办法貌似是重新构建数据库，但是这个在项目上线以后是绝对不可能的，谁能告诉我引发这样的错误的原因是什么吗，因为我目前不知道这个错误是怎么来的，所以谁能告诉我把这个错误再现的原因也可以阿，大哥大姐们小弟求解决方案

不然我要被fire了
