Description
Summary
The Confluence upgrade from 5.6.x to 5.10.x failed if the FK9228242D16994414 constraint missing from space table. The upgrade failed because Confluence is attempting to delete the constraint which does not exist in the table.
Step to replicate
- Drop the FK9228242D16994414 from the spaces table
ALTER TABLE spaces DROP FOREIGN KEY FK9228242D16994414
- Upgrade the Confluence from 5.6.x to 5.10.x
Expected Result
The upgrade is successful
Observed Result
The upgrade failed with the following error.The error indicate that the Confluence hit into NullPointerException when it try to delete the FK9228242D16994414 constraint which does not exist. By right the Confluence should have detected that the constraint is missing and skip the constraint deletion task since it doesn't affect the end result of the upgrade.

Workaround:
Add the constraint back to the spaces table.
ALTER TABLE spaces ADD CONSTRAINT FK9228242D16994414 FOREIGN KEY (SPACEGROUPID) REFERENCES spacegroups(SPACEGROUPID);
