Ian Boston commented on SHINDIG-728:
------------------------------------


Not being Guice expert, I would have thought a 

Object o = injector.getInstance(clazz);
if ( o != null ) {
   return o.getClass();
}
return clazz;

would be simpler.

Also I am not 100% certain that the interface check is safe, its probably 
possible to map an concrete class to an abstract class, which is going to give 
a class that cant in created.

But anyway, I am no Guice expert and from your use of  getProvider() I guess 
you are.

> Currently, the social-api uses some clever annotation magic to find its

> This code actually does not work with custom object implementations.
