> With multiple threads that write messages to a mina session.
> Sometimes i have this exception trace:

> I've mad some debug on mina source code and i've found that in ProtocolCodecFilter ther's this code at line: 446:
> if (future == null) {
>                 // Creates an empty writeRequest containing the destination
>                 WriteRequest writeRequest = new DefaultWriteRequest(null, null, destination);
> But this method doesn't work because seeing DefaultWriteRequest constructor ther's this code:
> public DefaultWriteRequest(Object message, WriteFuture future, SocketAddress destination) {
>         if (message == null) {
>             throw new IllegalArgumentException("message");
>         }
> Should be a bug.
> In my case i have this exception but i don't have some real problem. I think that many flush on same session 'steal' messages to write on flush each other.
> I don't have application problem. The messages seem to arrive at client side, but i have some stack trace exception and after session close i've seen from jmx that there are some statistics.writeScheduledMessages with none sessions active.
