Exception Handling in the provided Channel Handlers

[Utkarsh Srivastava]

Hi,

I want to use some of the provided channel handlers, e.g.,
LengthFieldBasedFrameDecoder. However, my question is what happens if the
client sends a malformed packet, e.g, one that has a huge length encoded in
the first 4 bytes. Currently, the handler throws an exception which will
probably cause the connection to be closed on the client.

I would instead want to send a nice error message back to client. How can I
do that?

Thanks
utkarsh
