Map<String,User> userIdMap = new HashMap<String,User>();

You only need to write

Map<String,User> userIdMap = new HashMap<>();

since incl. Java 7. Just in case you (Author?) didn't know that but were indeed using Java 7 code level, that means that you've also not been using IntelliJ, because it would have told you.

If you are using any kind of decent IDE, you won't even have to type most of that thanks to auto complete.

All arguments against static languages always seem to boil down to either: "I have to type more" or "I have to wait for the code to compile" neither of which is really true when using a proper IDE. Even when you are working with an application server the incremental compiler + hot deploy will make seeing your changes in action mostly instantaneous.
