Alex commented on DIRMINA-45:
-----------------------------
This fix helped. Now I can send messages but only for awhile.
If I start sending them fast I still get that exception, sometimes on client,
sometimes on server.
java.lang.IllegalStateException: doDecode() can't return true when buffer is
not consumed.

org.apache.mina.protocol.codec.CumulativeProtocolDecoder.decode(CumulativeProtocolDecoder.java:109)

org.apache.mina.protocol.io.IoAdapter$SessionHandlerAdapter.dataRead(IoAdapter.java:135)

org.apache.mina.io.AbstractIoFilterChain$2.dataRead(AbstractIoFilterChain.java:150)

org.apache.mina.io.AbstractIoFilterChain.callNextDataRead(AbstractIoFilterChain.java:364)
If my decode returns NEED_DATA it works fine no matter how fast client sends
messages.

> Project: Directory MINA
> Type: Bug
> Versions: 0.7.1
> Environment: JDK1.4.2
> Reporter: Alex
> Assignee: Trustin Lee
> Fix For: 0.7.2
>
> I am not sure if it is a bug or I just misunderstood something.
> I am implementing a protocol and use Demuxing* classes.
> When I return MessageDecoder.OK from my MessageDecoder's decode method, MINA
> tries repeatedly calls this method again. If I return
> MessageDecoder.NEED_DATA everything goes fine.
> So, I would expect completely reversal behaviour.
> I checked CumulativeProtocolDecoder and DemuxingProtocolCodecFactory classes.
> In CumulativeProtocolDecoder.decode it says that doDecode is invoked
> repeatedly until it returns false. Fine. But what "false" means here? I would
> guess that it means that buffer was completely decoded and no more data is
> needed. But DemuxingProtocolCodedFactory.doDecode returns true if decoder
> returned MessageDecoder.OK and false if decoder returned
> MessageDecoder.NEED_DATA. Isn't wrong here?
