I have a desktop application which uses an embedded database and is required
to stay up all the time.

I need to perform database maintenance operations, such as rebuilding
indexes, while the application is up. It is acceptable for the database to
become inaccessible for a period of time as long as the application can
re-connect to the database after the maintenance period.

I get an exception shown bellow when calling
FBMaintenanceManager.validateDatabase() from a separate Java thread inside
of my app. How can I work around this exception and is this the right way to
perform maintenance of embedded databases?

Thanks,

Alec
