Be careful: Map is not a subinterface of Collection

You can build an instance of all the classes implementing subinterfaces of Collection (Set,List,Queue...)

What happened when you tried? What did you discover in the API documentation?
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
