public class BridgeHandler
A simple MessageHandler implementation that passes the request Message directly to the output channel without modifying it. The main purpose of this handler is to bridge a PollableChannel to a SubscribableChannel or vice-versa.
The BridgeHandler can be used as a stopper at the end of an assembly line of channels. In this setup the output channel doesn't have to be set, but if the output channel is omitted the REPLY_CHANNEL MUST be set on the message. Otherwise, a MessagingException will be thrown at runtime.
