--------------------------------------------------------------
JBPM 5.1 seems unstable on the concurrent request happen. It seems a critical issue when we using persistence humantask on JBPM5.
Attachment are our code , normal logs and error logs.
 We found that the the error logs missing two line as the screenshot (MissingOneUpdateInErrorLogs.jpg) shown. After that, the task cann't be finished by the next steps.Not sure it is cause our code or the JBPM API. There are not any error reported from JBPM API. 
Please help us for analysis this problem, it would be nice if you can hlep us to fix those error data,no metter by DB update or JBPM API.
