Repro steps.

npm --prod --build-optimizer

Build is working without any issues

Starting the app I got a runtime exception

main.533cf46….bundle.js:1 ERROR Error: Uncaught (in promise): TypeError: f.Observable.defer is not a function

angular: 4.3.1
angular-material: 2.0.0-beta.8

using it without --build-optimizer it works without any issues

the defer is comming from angular-jwt

https://github.com/auth0/angular2-jwt/blob/435b8fc48415e57da40a788777a53ba37c906620/angular2-jwt.ts

but it's imported correctly there. I'm not sure why it's not working.

The log given by the failure.

Desired functionality.

Mention any other details that might be useful.

getting same issue with 1.3.0-rc.1 using same angular2-jwt

Edit: worth checking out the angular2-jwt beta that uses interceptors and the new 4.3 http lib. No more use of defer either.

This is indeed a problem with the build optimizer, related to angular/devkit#51. Will fix.
