Mike Matrigali updated DERBY-4741:
----------------------------------
Urgency: Normal
Labels: derby_triage10_8 (was: )
triaged for 10.8.
A lot of progress has been made on this issue, and it looks ready for 10.8.
Work is being done incrementally, probably soon should close this one based on
checked in work, and log a new one to track possible work post 10.8.
> Make embedded Derby work reliably in the presence of thread interrupts

> When not executing on a small device VM, Derby has been using the Java NIO
> classes java.nio.clannel.* for file io for extra concurrency.
> If a 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 store can be left in an inconsistent
> state, although no data is corrupted, and we therefore have to return a
> database level error to perform shutdown and recovery. This means the
> applications can no longer access the database while a shutdown and reboot
> including a recovery is taking place.
> 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.
