changes from Mina 2.0.0-M3 to 2.0.0-M6 to 2.0.0-RC1

[Vijay K Pandey]

Hi,

I have an application which has a very simple scenario of sending Java 
POJO(serializable) objects from Mina client to server and client waits for the 
response.

It was all working very fine with mina-core-2.0.0-M3.jar but looks like 
something has changed in  mina-core-2.0.0-M6.jar and mina-core-2.0.0-RC1.jar 
where on several messages mina server receives the message from client ( both 
process running on same machine) after a delay of 5 seconds. I can see that on 
client side LoggingFilter has written the message but then there is a delay on 
server side when it is received.

I ran  the test on the same "dataset" for the above 3 versions of MINA and - M3 
runs fine without any issue and there is no delay. I am testing this in a 
controlled environment where at any given point of time only 1 message is sent. 
Only after the response is received, does the second message is sent out.

Message is basically  - an array List - have 3 members where2 members are of 
string type and  1 member is HashMap of around 12 objects(11 are simple 
primitive wrappers and 1 POJO - having 6 primitives wrappers)

Can someone point me to the right direction?

Thanks
Vijay
