Upgrading from Versions of JIRA Prior to 3.1 Results in 'SAXParseException The Character Sequence' Error

When importing an XML backup made in JIRA 3.1 or lower into a newer version of JIRA, the import fails with following error:

Exception occurred: org.xml/sax.SAXParseException: The character sequence "]]>" must not appear in content unless used to mark the end of the CDATA section.


JIRA versions prior to 3.1 generate XML backups containing incorrectly escaped CDATA sections. See JRA-4980.


As per [JRA-4980@JIRA], create a new backup from your instance of JIRA 3.1 or lower:

  1. Replace the jar file <jira install>atlassia-jira/WEB-INF/lib/ofbcore-entity-2.1.1.jar with the one attached to JRA-4980
  2. Perform the export
  3. If an error like Parser has reached the entity expansion limit is observed in JIRA log, add a JVM option -DentityExpansionLimit=100000
