Issue Summary

When a user gets the latest JIRA Cloud backup from their Cloud instance and migrate this on to their JIRA Server instance that is connected to an Oracle database, they get the error seen below:

Steps to Reproduce

1. Install JIRA 7.1.9
2. Connect the JIRA instance to an Oracle database.
3. Get a JIRA Cloud backup.
4. Restore the cloud backup on to the JIRA instance from Admin > System > Restore system
   • During restoration, there has been 2 observed behaviors:
     • JIRA fails at about 90% and on restarting the instance you see the above error.
     • JIRA completes the import and shows you the login screen but should you restart JIRA for any reason, you would see the above error.

Error occurs even if you restore to postgres first and then migrate the backup to oracle from the JIRA UI

Workaround

The instance seems to be restricted to Oracle as I have tested this on H2 and Postgres and the issue could not be replicated.
