> From Rodrigo Kumpera's report:
> Great work with mina, it do makes writting nio servers easy. I=C2=B4m
> writing a filtering server and have the following scenario:
> 1-incoming connections, using ServiceRegistry with IoHandler.
> 2-filtering is done in a separate pool (using doug lea's
> util.concurrent package)
> 3-fowarding the result to another server, using SocketIoProcessor and
> IoThreadPoolFilter.
> So fair I=C2=B4ve been able to fine tune the thread pool used by the
> ServiceRegistry (1).
> My problem is with (2) and (3), I want to have a single thread pool to
> be shared by the 3 stages of the server.
> With the filtering stage I=C2=B4m thinking about playing with
> IoThreadPoolFilter implementation to use util.concurrent and expose
> it's interface.
> My problem when using a thread pool with the last stage, when
> connecting to foreign hosts, is that it throws the following exception
> under moderate load:
> java.nio.channels.CancelledKeyException
> at sun.nio.ch.SelectionKeyImpl.ensureValid(SelectionKeyImpl.java:5=

> at sun.nio.ch.SelectionKeyImpl.interestOps(SelectionKeyImpl.java:5=

> I tried to use the same IoThreadPoolFilter with an instance of
