body: Hmm, strange that after the**Caused By** section of the stacktrace there isn't anything much to describe the problem. Might be related to the bug report here: [https://jira.atlassian.com/browse/CONF-27056?focusedCommentId=409822\&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel](https://jira.atlassian.com/browse/CONF-27056?focusedCommentId=409822&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel)

Can you try the workarounds mentioned in the bug report above?   
1. Remove the due date from all the issues  
2. Set the JIRA language to English once again  

If its still not solved I recommend you raise a support request to Atlassian about this.

comments: author: Jinrui Mai
body: 1.Do you mean "remove the due date" is to hide the due date column in the Issue list?

2.The **Indexing language** and the **Default language**in the General Configuration page in Jira is also english,but no effect.
