Description

Currently NullResponseMessage and Ping report a wrong expected size (== 1500): it means that the allocated Netty buffers will be much bigger then necessary eg null is 13 bytes, while null v2 is 21.

 

In addition, NullReponseMessage could be cached if the transport channel won't use any resend cache, greatly reducing the memory used under load.
