> When not executing on a small device VM, Derby has been using the Java NIO 
> classes java.nio.clannel.* for file io.
> If thread is interrupted while executing blocking IO operations in NIO, the 
> ClosedByInterruptException will get thrown. Unfortunately, Derby isn't 
> current architected to retry and complete such operations (before passing on 
> the interrupt), so the Derby database can be left in an inconsistent state 
> and we therefore have to return a database level error. This means the 
> applications can no longer access the database without a shutdown and reboot 
> including a recovery.
> It would be nice if Derby could somehow detect and finish IO operations 
> underway when thread interrupts happen before passing the exception on to the 
> application. Derby embedded is sometimes embedded in applications that use 
> Thread.interrupt to stop threads.
