> Project: Directory MINA
> Type: Bug
> Reporter: John K Peterson
>
> On my system (Linux 2.4.22/JamVM 1.4.2/Classpath 0.90), ApacheDS gets stuck
> in SocketAcceptorDelegate.unbind.
> SocketAcceptorDelegate.unbind does the following:
> 1) creates a cancellation request
> 2) starts up a worker thread
> 3) puts the cancellation request on the cancelQueue
> 4) wakes up the worker thread's selector
> 5) waits for the cancellation request to be done
> The problem is that 4) assumes that 2) has gotten the worker thread to point
> where it has called selector.select(). However, there's no guarantee that
> the worker thread has gotten that far, in which case the wakeup occurs before
> the select and then the select hangs.
