@Emmanuel
Sometimes i get the following Exception, which appears after every decode once
it occures:
org.apache.mina.filter.codec.ProtocolDecoderException:
org.apache.mina.core.buffer.BufferDataException: dataLength: 1996751083

my Fiterchain:
fillterChain.addLast("compress", new CompressionFilter(COMPRESSION_MAX));
filterChain.addLast("codec", new ProtocolCodecFilter(new
ObjectSerializationCodecFactory(classLoader)); );
filterChain.addLast("logger", new LoggingFilter());
I hope it helps...

> Key: DIRMINA-653
> URL: https://issues.apache.org/jira/browse/DIRMINA-653
> Project: MINA
> Issue Type: Bug
> Components: Core, Filter
> Affects Versions: 2.0.0-M4
> Environment: Windows Vista 64-bit
> Reporter: Mauritz Lovgren
> Fix For: 2.0.0-M5
>
>
> I am writing a stress-test that tests multi-thread safetyness of our
> stateless encoder / decoder under heavy load and I am observing that messages
> are silently lost during session.write(Object), (the lost messages do not
> seem to reach the underlying socket buffer at all).
> I am using one encoder / decoder that is stateless. No executor filter, only
> the filter codec and a basic io handler.
> Synchronizing on the session.write makes the problem go away;
> synchronized (session)
> {
> future = session.write(message);
> }
> Do I really have to synchronize on the session to solve this issue?
