Reloading services after changes to included property values

Yes, we have. The project you are referring to below works fine for a POC. 
It's not without limitations but it works fine. It is however perfectly 
unsafe for production use. It was just an idea at the time I started playing 
around with refreshable Spring contexts.

To "correctly" do this, you have the following options:

1. Ditch Spring's property placeholder machinery, use your own. Most folks 
that go this route tend to use Apache's configuration lib
2. Figure out how to rework the POC below to work with Spring4 and make it 
3. Use @RefreshScope and Spring cloud to handle this.

#3 is the best option.
