byte array and Object Encoder , Object Decoder

[manish_iitg]

Hello,

I have noticed a strange error recently in my application which users. 

When ever i send a byte[] from server to client using Object Encode -
Decoder handlers in my pipleline,
I get the below error. 

I am using netty-3.1.0-Beta3.jar and jdk6 update 11.

I think the below error is related to JDK6 issue
(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6500212) although i am
not sure about it. Could you check this out let me know a work around for
this.
