Thanks everyone

I'm afraid your h2 database has failed.  This happens a lot, and it's the reason Atlassian tell you not to use it for anything that really matters (dev and test systems can be recreated, no huge loss if they fail)

The best you can do is check the "exports" directory for a recent backup, fire up a new installation and import the backup into it.

Whether that works or not, you need your next Jira install to use one of the four supported databases.
