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 i0ve 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.
