Bryan Pendleton commented on DERBY-2367:
----------------------------------------
Thanks for tracking this code down, Raymond, and I'm glad to hear that you've
had success with modifying it. I don't think we should mark the issue resolved
yet. Perhaps somebody who's familiar with that code can shed some light on what
it's doing and whether we can make it more general.

> We use the network server variant of Derby.
> The first ( creating ) connect is always successful.
> The folders log and seg0 are created and populated successfully.
> We can create tables and data without a problem.
> We checked that by copying the folder to windows and connecting
> and seeing our data being there.
> But all other ( i.e. a second ) connection attempts to an existing DB foilder
> fail
> with forementioned exception.
