Jeff Mckenzie commented on DERBY-4589:
--------------------------------------

If the database is completely empty and has no tables, why not just recreate 
the whole thing from scratch?

You would only need a little flag somewhere for this. It gets written to once 
the database is fully created and opens normally. If it is in the wrong state, 
delete and recreate the database.

OTOH, if you have definitely identified the problem, carry on...

> I have found a database in my application that prevents startup due to it 
> being corrupted. 
> The driver reports that the database does not exist, even though it does. 
> Then when my app tries to create the database using ;create=true; on the URL 
> it fails.
> I think this happened due to the app being killed in Task Manager while it 
> was creating the database.
> I have the database saved so that you can reproduce the problem. (I'm not 
> sure if I can attach it yet)
