Description

For example when people poll files, then they may want to react if there is no files to pickup. Currently you would have to use a poll strategy, but we should add an option you can configure on the endpoint, to have it emit an null message instead.

sendEmptyMessageWhenIdle - false - If this option is true, and there was no messages to poll, then we simulate processing a single message, by sending an empty message.
