Summary

According to Supported Platforms, JIRA 6.4 only supports Java (JDK or JRE) versions 7 and 8, and also Oracle 11g. However, the JDBC driver shipped with JIRA for connecting with Oracle, 11.2.0.2.0, is not supported for use with Java 7 and 8 according to Oracle JDBC FAQ.

Expected Behavior

Ship JIRA with an Oracle driver compatible with other supported platforms.

Actual Behavior

JIRA ships with Oracle JDBC Driver version 11.2.0.2.0, which doesn't support Java 7 and 8.

Steps to Reproduce

N/A

Workaround

Download Oracle JDBC driver version 11.2.0.4.0 (latest, at time of writing) from this Oracle page and replace the existing ojdbc6-11.2.0.2.0.jar file under <JIRA_INSTALL>/lib.

JIRA needs to be restarted in order to use the new driver.
