As per customer, no changes has been made to the system prior to occurrence of this issue.
Cause
The issue is due to a bug with Oracle JDBC Driver which is fixed in Oracle patch 19158500. If a Clob is accessed with the JDBC driver that is exactly 8000 characters long it returns an incorrect value
 
Resolution
1. Download Oracle JDBC driver(ojdbc7.jar) from this article's attachment. This Oracle JDBC driver includes Oracle patch 19158500
2. Replace /home/oracle/wildfly-8.2.0.Final/modules/com/oracle/main/ojdbc7.jar with the Oracle JDBC driver obtained from RSA Customer Support
3. Restart WildFly application server i.e. acm restart
 
Notes
The official Oracle patch 19158500 to fix the Oracle JDBC driver error will be included in all future RSA Identity Governance and Lifecycle releases.
