Jira升级小插曲
Old Version: Professional Edition, Version: 3.0.3-#75
New Version: Professional Edition, Version: 3.12.3-#302
backup data to xml文件后，在新版本上Restore Data from xml，Error：
Failed to import data: Error in action: com.atlassian.jira.action.admin.DataImport@1ddcd5f, result: error Error
parsing export file. Your export file is invalid. This may be due to a CDATA bug in older versions of JIRA
(http://jira.atlassian.com/browse/JRA-4980). Exception is org.xml.sax.SAXParseException: The element type "body"
must be terminated by the matching end-tag "</body>".
发现这是jira旧版本的一个bug，找到fix pack，更新到服务器上，重新备份导出，恢复成功。
fixpack:
http://repository.atlassian.com/ofbcore/jars/ofbcore-entity-2.1.1-atlassian-06122004.jar
and copy to your WEB-INF/lib/ directory (atlassian-jira/WEB-INF/lib/ in JIRA Standalone; webapp/WEB-INF/lib/ in JIRA
WAR/Webapp). You must also delete the old WEB-INF/lib/ofbcore-entity-2.1.1.jar file, which this replaces.
