New Revision: 1171625
URL: http://svn.apache.org/viewvc?rev=1171625&view=rev
Log:
Introduce ProtocolTransport a service implemented by the transport
implementation (e.g: netty) and used by generic Protocol sessions (e.g:
SmtpSession).
This way the session does need to depend on the transport implementation but
depends on it at runtime.
