Re: Gin module binding using annotatedWith and AsyncProvider

Well, I have to apologize - I have it working now, although I don't think I actually changed anything related to the problem.  FYI, the error message I printed was incorrect and not the cause of the problem - the actual annotation I was using was indeed @Async and not @Special, which I changed in the code examples I gave to avoid any implication that it wasn't just a made-up annotation.

As an aside, I also got a Provider version working, which was a bear. I ended up creating a proxy class that wrapped an of the class I wanted (and implemented the same interface), then passed all the methods through to the contained object, then added another method to kick off the runAsync call.  Two things I don't like about that approach are:
  • I ended up explicitly instantiating my class in the runAsync call, which seems to render some of the injection concept moot
  • because of my additional method to load the proxy, I either had to add that to my interface, or typecast what I got from the provider to the proxy class in order to invoke it.  I chose the latter.
