ProtocolCodecFilter.flush
Simone Melchiori created DIRMINA-973:
----------------------------------------
Summary: IllegalArgumentException thrown on ProtocolCodecFilter.flush
Key: DIRMINA-973
URL: https://issues.apache.org/jira/browse/DIRMINA-973
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 2.0.7
Environment: Windows Vista, jre 1.7.0_40
Reporter: Simone Melchiori
With multiple threads that write messages to a mina session.
Sometimes i have this exception trace:
org.apache.mina.filter.codec.ProtocolEncoderException: java.lang.IllegalArgumentException: message

Caused by: java.lang.IllegalArgumentException: message

at org.apache.mina.filter.codec.ProtocolCodecFilter$ProtocolEncoderOutputImpl.flush(ProtocolCodecFilter.java:448)
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.
