byte array and Object Encoder , Object Decoder

["이희승 (Trustin Lee)"]

Hello Manish,

Thanks for reporting the problem.  There was a bug in ObjectEncoder -
https://jira.jboss.org/jira/browse/NETTY-178

I've just checked in the fix at revision 1445.  You could wait a couple
hours and pick up the nightly build to see if the fix works, or build
from trunk by yourself.  Please let me know if my fix worked for you.

HTH,
Trustin
